I have to say that it really is a terrible book for students to learn from who have never had much exposure to non-calculus math and the concept of the "mathematical proof". It skims over topics without providing enough exposition on the topics to allow students to have a fair grasp on the subject. This may just be the nature of teaching discrete math, but there seem to be far too many topics that Truss is trying to squeeze into too small of a space. He tries to throw in some more advanced topics such as formal machines and complexity theory, but only at the cost of having the overall quality of the material be watered down. Sadly, though, from what I have heard, this is the best current intro discrete math book out there. I will have to agree with the other reviewer that it seems as if Truss is trying to cram lots and lots of discrete mathematics into an indiscrete stack of 500pp but i think he has done very well. At least in addressing those who need to skim over the material quickly, though they would love instead to relish on Grimaldi's.

On learning mathematics from scratch, again. How would you chart a course for math studies? I've read in various places that you can possibly self-teach yourself math from just dover books and schaum's outlines, Background: I've got a formal math education up through calc 2. Unfortunately, I never really "got" the math, and mostly just went to get a grade and get out. This sucks, especially since I'd like to really learn more about physics and my lack of true calculus "understanding" seemed to hold me back. Granted, my math is probably a lot more advanced than most of the population, I'm just not satisfied with it. I want to go back to Algebra, Geometry, Trigonometry and then move into Calculus, Linear Algebra, Diff Eq, etc, more like an engineering math background, spending as little money as possible (hell, I'll probably be able to find Dover books at the library, you know?.. and yes, this means Stewart & the like are right out..), andYou don't want to spend money, which is fine, but how flexible is your time? If you can fit it in, you are likely to be able to audit classes at your local university free of charge. I always just walked in on the first day and asked the professor if they minded me auditing. I haven't had a single one turn me down (although I was mostly auditing high level - read "small" - classes, calculus is likely to be a packed lecture hall). The money is for the grade/degree, not the education. There's always the original source material. It's all old enough that you can get it for free (even in translation to English), and it has to explain the principles to as a new line of thinking. Since you're relearning the material, you should have the background to follow it. It's a very proof heavy way to do it, but it would definitely get you there. Quite true. This is fairly ridiculous but that's how world works now. You are supposed to be going to university to become competent enough to do a well paying job (for example), but in practice you're just doing it to get a paper that correlates somewhat (but far from perfectly) with competence, and gets you through the door; the companies just eat up the losses caused by incompetence, or go belly up if losses are too great, or rely on their own testing, at least in the software industry. The universities bundle the certification with education, that's just a marketing tactic that works far better for them than offering education and certification as separate products. Very small percentage of their customers are interested in education per se, so the education itself is easily obtainable for freeThanks for the offer, but I had Stewart in school. Man that book gave me a headache. :/ Quote: You don't want to spend money, which is fine, but how flexible is your time? Not very right now. I'm signed up for some film classes in the spring starting mid-february, but no math/physics. This is more of just an exercise to try and "right" something I feel like I cheated myself out of (or was cheated out of by my instructors who were more interested in passing students than teaching them). who knows where it will lead later. I figure I'll work through the above to try and get that foundation I want, then return to my physics interests. Some areas I'll suggest you look into aren't covered in Mathematician's Delight. One of them is generally termed 'discrete math' - as opposed to the continuum of trig/calculus. A little bit of combinatorics can go a long way in solving practical problems that in any way involve questions of "how many" - it's the study of counting. From there, graph theory can offer an interesting perspective on the world. You may also want to poke at some abstract algebra or topology for fun. The former offers some very nice views of how to understand everything else you'll see in a more coherent framework. I'll also suggest at least some study of formal logic, and the attendant rigor in proofs that comes with it. The basic premise is that anything we can prove can be described in a form that can be verified entirely syntactically - solely checking whether each step followed the rules, rather than the reader having to understand the meaning (semantics) of each step. It starts with basic school arithmetics and takes you all the way through the foundations of engineering maths (discrete mathematics, logic, calculus etc.), at least for a BS it is all that you will need. I haven't read dio's suggestion, but I have to wonder whether an engineering math book is going to fit the "focusing on the WHYS not just the HOWS" requirement of the OP. I've used a few engineering math books as references in my day, and while they're good for that purpose, they tend to be light on theory. Stroud is an excellent textbook i own both basic and the advance version. Very simple to learn what you need out of. BUT ITS NOT WHAT YOU ARE AFTER Stroud plays fast and loose with many things my lecturers (Mech Eng at a good uni) recommended Erwin Kreyszig's Advanced Engineering Mathematics and were very disparaging of stround saying it cheated. Then again i learnt of stroud becuase it was easy when it counted and that is why i own. Got doing second order differentials in a day took me 5 days with kreyszig when I relearnt it for the 3rd time. But with Kreyszig i understood what I was doing more so that is what i would go with. Engineering Maths books sound like they might be pitched at the right level for you. They start at Calc and work their way up and they are designed for us dumb engineers. I Wish you luck in your quest. There are many things i would like to do with hot pokers than learn maths again. What is your overall goal? Having in mind something like "I want to learn topic X" is a much better goal than "I want an engineering level math background". There are a lot of things wrong with the standard engineering level mathematics curriculum (beginning with the fact that there even is such a thing as a standard curriculum). A even better goal is "I wanted to solve problem Y" or "understand phenomenon Y". I always used signal processing as a goal since I was into recording music. I'm in a similar boat...having recently experienced a new interest in mathematics after hating it pretty much my entire life. Quote: andI can't help you for algebra or trig, but for calculus, I definitely recommend MIT's OpenCourseware. I downloaded the PDF from the Intro to Calculus course and it pretty much has the "why" of calculus in the first few pages. That depends on what you end up needing to use the maths for? I'm guessing physics, and if you mean degree-level physics that's some serious ball-achin' mathematics if you get into the heavy stuff... I think Stroud is great for engineering students, who are of course his target audience, but maybe not so hot for maths/physics students. I also used Kreyzig, as it was the recommended book for my degree, but still don't feel that it helped with the WHYs which is what you say you are interested in. When it really comes to understanding maths and developing your intuition and insight, I would first of all say go back to absolute basics and revisit even the basics such as arithmetic. Really build up your familiarity with the fundamentals. Many mathematicians express great familiarity with numbers themselves and I think that's worth exploring. Secondly, practise and practise and practise. Dont' just learn methods of solution, but practise your mental arithmatic too. Familiarity comes with practise but often taught courses pressure you to keep advancing your topic of study, which can be lethal to your chances of success the moment you over-advance... Thirdly, try reading books that explore mathematical techniques, styles of thinking and which also examine the various *different* ways to approach problems. It should help you find your natural approach to mathematics (everyone thinks differently) and help you start to see past the mechanics of 'solutions'. I must confess I'm a bit short of good suggestions for this, but in general I'd say try to read and explore as widely on each topic as possible. Lastly, try reading about mathematicians themselves, their stories and the stories of their work and discoveries. It's really very interesting to see how they each understood maths, how they felt and what drove them. It should help you begin to feel about maths as a *human* endeavour and not just make you feel like a human calculating machine This freaks out a lot of people, because they are used to subjects that are understandable on day 1, and students often get complexes about "not understanding it" and seriously shortchange themselves. I've often wondered why that was only in the teacher's guide, and not routinely told to students. For me, I found the knowledge that blundering around doing problems mechanically for the first few weeks is normal, and since I often "got it" within a week or so, I was actually above average, not struggling to keep up. My guess is that going back, you will "get it" tremendously faster, since you have covered it once. Plus, having seen other material that uses the math, you won't ever struggle with the "this is dumb. I'll never use this." cop-out I'm not convinced we all "got" Geometry on Day 1, let alone Shakespeare... but the basic point is probably a good one. I'm a class away from starting Linear Algebra and Diff equations, and I went back to school in my late 20's, so I had to take a lot of remedial stuffI really, really like math, I just admit to myself I'm not particularly good at it and do lots and lots of homework. I eventually got it with a hell of a lot of road bumps in the way. One other resource I didn't see mentioned in the thread is Khan Academy. They cover everything from elementary arithmetic to Linear Algebra, and everything is broken down into easy to digest 10-15 minute videos, so it's easy to go back and review something you might have missed or forgotten. What I find especially nice is that he tends to explain concepts in intuitive terms rather than just giving rote instructions for solving formulaic problems, and makes it easier to connect one concept to another. If you're feeling extra frisky, there are exercises that accompany the lessons with some nice progress-tracking toolsTHIS IS EXACTLY HOW I FELT IN CALC I and lead me to create this thread, actually. I passed Calc I & II but I felt extremely out-gunned and over-my-head because I forgot all the building blocks up to it. Even though I managed to pass, I was never satisfied with my performance and it still eats at me to this dayYou used that for your calc class? Nice, the math program where I went didn't pick that up until Real Analysis. We did use Spivak's Calculus text, though, and it did give a serious treatment to the principles and derivation of calculus[quote=MilleniX]We did use Spivak's Calculus text, though, and it did give a serious treatment to the principles and derivation of calculus.[/quote] Oops, I forgot. We also used Spivak. It's good, I think a clean introduction to multi-variable calculus and manifolds haveI find myself caught on all sides of the rigor wall, currently. I'm taking a numerical analysis class taught by an engineering professor. I already have an understanding of the "big picture" of the field, so I find the lack of rigor in the class super frustrating. I don't need someone telling me "real life" examples or explaining conceptual bits, I want the gory details. On the flip side, I have to keep up in algebra by shear memorization. High power tools are wielded without regard to life or limb. The logic is super precise. But, I could get the same treatment in a textbook versus copying well-worn notes from the board. So it feels like a giant waste of time (for all parties involved) not gaining any perspective from the professor's presentation. I still don't understand precisely what the OP wants out of his experience. If it's mathematics for mathematics sake, people have made the "classical" suggestions of learning calculus through Spivak and Rudin (I'll also toss out Apostol for calculus and Arnol'd for ODE). All I see in the original message is a list of courses you'd find on the resume of any vanilla engineering graduate. It gives no feel for where the true interests lie. What precise problems motivate you? I went into math trying to figure out the mathematics behind music technology. I learned differential geometry to understand general relativity and electromagnetism. I continued with analysis to deepen my understanding of signal processing. I simply learn mathematics better if I have a solid, nontrivial application in mind. (This is probably a reflection of my philosophy of mathematics.) I recently did a similar thing. I got all the way through Linear Algebra/Diff. Equations and a few upper-level physics classes before dropping out, and now I'm back trying to get my bachelor's and eventually a master's. I'm currently enrolled in Calc II and Physics I. First, it's easy to learn enough to pass a regular university-level course without sufficiently learning the material if you're intelligent. Auditing a course is a good way to keep you on track and give you information if you're self-learning, but it's all about the self-motivation and self-discipline if you want to master the materialSo it all depends on where your skills are at and what your ultimate goal is. If your math skills are better than mine were, or if you just want to learn some new interesting things you can take a different approach and do well at it. But if you're looking to get an expert level understanding, or a job in the field (or if you're looking to apply what you learn to a different field like engineering), you'd definitely be best off relearning *everything* and putting a good amount of work into it. If your really want to move into the field and *excel* at it (or if you're just a giant nerd and you want to learn as much out of it as you can ) you're going to need to revisit most of the stuff you've learned in the past. It's frustrating, but that's my experienceMilleniX wrote: We did use Spivak's Calculus text, though, and it did give a serious treatment to the principles and derivation of calculus. Oops, I forgot. We also used Spivak. It's good, I think a clean introduction to multi-variable calculus and manifolds. Not that one. Again, I'm pretty sure that's intended for upper-division math majors ("The formal prerequisites include only a term of linear algebra, a nodding acquaintance with the notation of set theory, and a respectable first-year calculus course"). I mean CalculusHere. This absolutely killed me. The teacher would go over a subject in class. Cool. I got it. Didn't bother with homework. When it was time to take the test, I easily passed and moved on. I never did learn how to study. Didn't need to, until algebra II. Now, I'm in the same place as MongoMania The key thing is that integration by parts is a heuristic, there's no algorithmic iteration that always leads you to the solution. You need to strategically pick u and v based on what simplifies the problem. The goal is to turn an integral you can't solve into some stuff minus an integral you can solve. Don't iterate unless absolutely necessary. If you don't immediately see how to solve the resultant integral (by substitution or whatever), go back and pick a different u and v, rather than trying to use integration by parts again. Sometimes it is helpful to do it more than once, but it is easy to make a mess trying, so don't do it unless you have exhausted the other possibilities. Ah, yeah, there's a cute trick with that. Do it twice and you should end up with some stuff plus something that looks like the original integral. Set it equal to the original integral, move that term to the other side, divide off the constant, and voila. If you don't get it in the next 10 min or so let me know and I'll latex it up.

Office Hours: Tuesday and Thursday 9:50-10:30 (Darwin 122, our classroom); by discovery; or by appointment. Please come to office hours if you have any questions about the course material or your progress. We're going to work on many concepts of early algebra, including some background in fractions that is often a stumbling block for students. Our goal is to become fluent in algebraic manipulations, to allow you to succeed in later courses which count on your algebra skills. "In its most common form, algebra is just an extension of the number system. For example, algebraic formulas often describe how one quantity depends on another. Determining gas mileage, predicting the amount of food needed for a party, and figuring the costs of renting videos are all examples of daily situations that require algebra. "Not every student needs to be able to derive the quadratic formula. But all should understand how a change in one quantity affects another and how to make decisions based on these relationships. In this sense, every student needs to master algebra. "Learning how to read, write, and do arithmetic may seem more important than learning algebra. But a lack of algebraic understanding can be just as debilitating as deficiencies in reading or arithmetic when ... trying for a good job." Course particulars CALCULATOR policy: Calculators are not to be used in this course. While they are valuable tools in many endeavors, they won't help you learn the concepts we'll be studying. ASSIGNMENTS: Homework will be assigned at the end of each class meeting. Keep all homework in a loose leaf binder. Indicate page of the text at the top of each page. A completely worked solution presented is expected. When drawing graphs use graph paper and a straightedge. QUIZZES will be given on a regular basis. They will include problems from your homework as well as other problems. You will be allowed to use your homework binder to answer questions on the quizzes. So it is important that the homework binder is kept up to date. The quizzes cannot be made up but you will be allowed to drop at least two of your lowest scores. A completely worked solution neatly and legibly presented is expected. The weekly quizzes will include problems based on prior weeks' material. The quizzes will take either of the following two forms: Form 1: You will be allowed to use your text homework binder to answer questions on FORM 1 quizzes. These quizzes will consist of two parts. The first part will consist of two or three problems taken directly from your homework notebook. The second part will consist of problems 'similar' to homework problems. You will be allowed to use your text homework notebook to answer questions on both parts of the quiz. So it is important that the binder, i.e. homework, is kept up to date. Form 2:These quizzes will be closed book and will be similar to the homework problems. They will be unannounced and you will not be allowed to use your homework notebook for these quizzes. EXAMS cannot be made up. You may replace your lowest exam score with your Final exam score. The Final is cumulative and must be taken. A completely worked solution neatly and legibly presented is expected. Resources Math Study Lab:Learning Skills Services and the Tutorial Program are co-sponsoring a Math 35 Study Lab for this semester. It will be Mondays 2-4 p.m. and Thursdays 10 a.m. – noon. First meeting is Thursday, September 2 in Salazar 1040. I highly recommend that you take advantage of this free service! You can just drop in on the occasions when you can make it. ELM: If you feel that you are in Math 35 only because of a bad test day – in other words, you believe you already know the material or could pass the ELM with a little more studying – you can take it again during the semester (October 9 and December 4). The web site has some information on the test (including description of the content of the test, under "Focus on Math" link), and is where you go to register. There is an $18 fee to take the test. If you take the October 9 test and bring me your score reporting showing a passing score prior to the final exam, then you don't have to take the final and you will receive a C for this course. If you pass either October 9 or December 4, then you won't have to take Math 45 in the Spring and can proceed directly to the GE math course of your choice. Online resources: The California State University has a new website at to help you if you want to take the ELM. This site has a practice test, and additional practice problems, for you to work on. If you want to do additional work to prepare, the ALEKS ELM tutorial which you can purchase for $35 through this site is a great deal. ALEKS also has a beginning algebra module, and you can use that for the same $35 fee – the fee buys you an 18-week license to use all of ALEKS. You can learn more about ALEKS, and try it out before you buy, at M*A*T*H Colloquium: This is our weekly lecture on various mathematical topics. The September 8 lecture will be particularly relevant for some of us. 5 extra credit quiz points if you attend and give me a 1-page writeup about the talk and what you learned.

Product Description Review From the reviews: MATHEMATICAL REVIEWS "There are many books about the theory of prime numbers and a few about computations concerning primes. This book bridges the gap between theoretical and computational aspects of prime numbers. It considers such matters as how to recognize primes, how to compute them, how to count them, and how to test conjectures about them¿The book is clearly written and is a pleasure to read. It is largely self-contained. A first course in number theory and some knowledge of computer algorithms should be sufficient background for reading it…Each chapter concludes with a long list of interesting exercises and research problems." BULLETIN OF THE AMS "The book is an excellent resource for anyone who wants to understand these algorithms, learn how to implement them, and make them go fast. It's also a lot of fun to read! It's rare to say this of a math book, but open Prime Numbers to a random page and it's hard to put down. Crandall and Pomerance have written a terrific book." AMERICAN SCIENTIST "…a welcome addition to the literature of number theory – comprehensive, up-to-date and written with style. It will be useful to anyone interested in algorithms dealing with the arithmetic of the integers and related computational issues." SIAM REVIEW "Overall, this book by Crandall and Pomerance fills a unique niche a deserves a place on the bookshelf of anyone with more than a passing interest in prime numbers. It would provide a gold mine of information and problems for a graduate class on computationl number theory." From the reviews of the second edition: "This book is a very successful attempt of the authors to describe the current state-of-the-art of computational number theory … . One of the many attractive features of this book is the rich and beautiful set of exercises and research problems … . the authors have managed to lay down their broad and deep insight in primes into this book in a very lucid and vivid way. … The book provides excellent material for graduate and undergraduate courses on computational theory. Warmly recommended … ." (H.J.J. te Riele, Nieuw Archief voor Wiskunde, Vol. 7 (3), 2006) "An absolutely wonderful book! Written in a readable and enthusiastic style the authors try to share the elegance of the prime numbers with the readers … . Weaving together a wealth of ideas and experience from theory and practice they enable the reader to have more than a glimpse into the current state of the knowledge … . any chapter or section can be singled out for high praise. … Indeed it is destined to become a definitive text on … prime numbers and factoring." (Peter Shiu, Zentralblatt MATH, Vol. 1088 (14), 2006) "This impressive book represents a comprehensive collection of the properties of prime numbers. … in the exercises at the end of each chapter valuable hints are given how the theorems have been attained. The chapters end with research exercises. The book is up to date and carefully written. … The volume is very vividly and even entertainingly written and is best suited for students and for teachers as well." (J. Schoissengeier, Monatshefte für Mathematik, Vol. 150 (1), 2007) "The aim of this book is to bridge the gap between prime-number theory covered in many books and the relatively new area of computer experimentation and algorithms. The aim is admirably met. … There is a comprehensive and useful list of almost 500 references including many to websites. … This is an interesting, well-written and informative book neatly covering both the theoretical as well as the practical computational implementation of prime numbers and many related topics at first-year undergraduate level." (Ron Knott, The Mathematical Gazette, Vol. 92 (523), 2008) From the Back Cover Prime numbers beckon to the beginner, as the basic notion of primality is accessible even to children. Yet, some of the simplest questions about primes have confounded humankind for millennia. In the new edition of this highly successful book, Richard Crandall and Carl Pomerance have provided updated material on theoretical, computational, and algorithmic fronts. New results discussed include the AKS test for recognizing primes, computational evidence for the Riemann hypothesis, a fast binary algorithm for the greatest common divisor, nonuniform fast Fourier transforms, and more. The authors also list new computational records and survey new developments in the theory of prime numbers, including the magnificent proof that there are arbitrarily long arithmetic progressions of primes, and the final resolution of the Catalan problem. Numerous exercises have been added. Richard Crandall currently holds the title of Apple Distinguished Scientist, having previously been Apple's Chief Cryptographer, the Chief Scientist at NeXT, Inc., and recipient of the Vollum Chair of Science at Reed College. Though he publishes in quantum physics, biology, mathematics, and chemistry, and holds various engineering patents, his primary interest is interdisciplinary scientific computation. Carl Pomerance is the recipient of the Chauvenet and Conant Prizes for expository mathematical writing. He is currently a mathematics professor at Dartmouth College, having previously been at the University of Georgia and Bell Labs. A popular lecturer, he is well known for his research in computational number theory, his efforts having produced important algorithms now in use. From the reviews of the first edition: "Destined to become a definitive textbook conveying the most modern computational ideas about prime numbers and factoring, this book will stand as an excellent reference for this kind of computation, and thus be of interest to both educators and researchers." <- L'Enseignement Mathématique "...Prime Numbers is a welcome addition to the literature of number theory---comprehensive, up-to-date and written with style." - American Scientist "It's rare to say this of a math book, but open Prime Numbers to a random page and it's hard to put down.

Most Helpful Customer Reviews on Amazon.com (beta) Amazon.com: 6 reviews 33 of 33 people found the following review helpful Standard reference on the subject.April 21 2003 By Decio Luiz Gazzoni Filho - Published on Amazon.com Format: Hardcover Unfortunately, modern factoing algorithms deserve a book on its own, and it's impossible to cover all the ground in the space alloted to them in this book. The authors do a pretty good job of introducing them, even if the explanation is unclear and a bit shallow at times, and they always reference other works on the field for further information they were unable to cover. Chapter 7, ``Elliptic Curve Arithmetic,'' is a great starting point for elliptic curve studies, with a no-nonsense introduction to the subject that is certainly enough for the algorithms that follow. These include Lenstra's Elliptic Curve Method of factorization; Shanks-Mestre's, Schoof's and Atkin-Morain's algorithms for assessing curve order; and Goldwasser-Kilian's and Atkin-Morain's primality proving algorithms. Almost as valuable as the rest of the book itself (at least for implementers) is the ninth and last chapter, ``Fast algorithms for large-integer arithmetic.'' Many of these can be carried over without effort to floating point, so the scope of the material is even broader than the authors claim. Having read parts of Knuth's ``The Art of Computer Programming: Seminumerical Algorithms,'' I can attest to the superb exposition of Crandall and Pomerance being a breath of fresh air in this field. This book belongs on the shelf of every programmer implementing multiprecision arithmetic for this chapter alone. 25 of 25 people found the following review helpful A Factoring "Bible"March 6 2002 By Ed Prothro - Published on Amazon.com Format: Hardcover This book has all the recent (2001) developments in factoring algorithms and related number theory.

But it is not all abstract number theory. The recurrent theme is how to compute these and how to use primes in other computationally intensive tasks. The book summarises centuries of effort. Notably with Goldbach's Conjecture about every even number>2 being the sum of two primes. But intriguing issues like the density of primes along the number line are gone into. Along with the Mersenne primes and prime producing formulae. An entire chapter discusses cryptography and related matters. Primes are at the heart of PKI and its RSA implementation. There is even a section briefly covering quantum computing and a quantum Turing Machine. Rather sparse detail because, well, the experimental results are still very new. Only baby steps have been forthcoming. The phase coherence difficulties are formidable. But it is a potentially vast area of future work. 2 of 2 people found the following review helpful This is not a book for casual reading, or indeed even for studious reading: it requires devotionMarch 30 2015 By James Kenney - Published on Amazon.com Format: Hardcover Verified Purchase This book is one of obvious authority, written by men far beyond gifted.

What Is Calculus? Calculus was invented as a tool for solving problems. Prior to the development of calculus, there were a variety of different problems that could not be addressed using the mathematics that was available. For example, scientists did not know how to measure the speed of an object when that speed was changing over time. Also, a more effective method was desired for finding the area of a region that did not have straight edges. Geometry, algebra, and trigonometry, which were well understood, did not provide the necessary tools to adequately address these problems. At the time in which calculus was developed, automobiles had not been invented. However, automobiles are an example of how calculus may be used to describe motion. When the driver pushes on the accelerator of a car, the speed of that car increases. The rate at which the car is moving, or the...

The aesthetic comparison alone, compared to my old manuals, is impressive. Here we have a book which has focused on the very finer details: excellent layout, enjoyable font, written and indented formulas and perfectly clear pictures. The smooth paper is very nice and it has a sturdy binding but not too stiff. Since the topic itself has complexity in its DNA, it is presented well, makes it interesting (almost intriguing) for students in the first year of Computer Science ( the course on which the book is based). The approach is a bit outside the box, since it presents examples first - almost all the typical courses in Italian universities do this after the mathematical theory/algebraic. The book is divided into 2 parts practically of the same length and number of pages. In the first part the reader is exposed to: examples from games at the Tower of Hanoi, all with resolution explained in detail, both in words and through equations and algorithms. They are also offered exercises to be solved and ideas for projects. The first, fortunately, have solutions and answers in Appendix. The second is the mathematical theory which acts as a glue to algorithms - from algebra to number theory of quantifiers. Everything is explained in English but it is easy to understand by non-native English speakers (just a decent knowledge of language is necessary).Read more › a lot of exercises so you can practise what you've learned. i bought it a few months ago and only read the first 100 pages or so. did help me with my uni work but should've bought it earlier to have enough time to read all the content. but overall its a good book which covers interesting APS concepts this book is hard to understand, the layout is bad and it jumps a lot! the logic could be better explained, rather than using boolean, and at times even the simplest things are said in the hardest way!!!

College Algebra with Trigonometry : Graphs and Models with MathZone: MandatoryMathematical reform is the driving force behind the organization and development of this new text in college algebra and trigonometry. The use of technology, primarily graphing utilities, is assumed throughout the text. The development of each topic proceeds from the concrete to the abstract and takes full advantage of technology, wherever appropriate.The first major objective of this book is to encourage students to investigate mathematical ideas and processes graphically and numerically, as well as algebraically. Proceeding in this way, students gain a broader, deeper, and more useful understanding of a concept or process. Even though concept development and technology are emphasized, manipulative skills are not ignored, and plenty of opportunities to practice basic skills are present. A brief look at the table of contents will reveal the importance of the function concept as a unifying theme.The second major objective of this book is the development of a library of elementary functions, including their important properties and uses. Having this library of elementary functions as a basic working tool in their mathematical tool boxes, students will be able to move into calculus with greater confidence and understanding. In addition, a concise review of basic algebraic concepts is included in Appendix A for easy reference, or systematic review.The third major objective of this book is to give the student substantial experience in solving and modeling real world problems. Enough applications are included to convince even the most skeptical student that mathematics is really useful. Most of the applications are simplified versions of actual real-world problems taken from professional journals and professional books. No specialized experience is required to solve any of the applications.

Oceanography at Fitchburg State University Challenges to using math in introductory geoscience Fitchburg State University is a four-year public institution with a diverse student population, which includes those traditionally underrepresented in higher education (first-generation, low-income, and students with disabilities). Approximately half of our incoming students require developmental math coursework, but often enroll in science classes prior to completing them. The result is that many students (mostly non-majors) in our courses lack requisite math skills, but they are taking these courses alongside science majors. The goal of implementing TMYN in Oceanography is to help those under-prepared students gain the math skills needed to succeed in the course, allowing more in-class time for content. The online format of the modules are also beneficial for our students, most of whom commute to campus or have off-campus employment. More about your geoscience course This course, which includes 2.5 hours of lecture and 1.25 hours of lab per week, is required for our majors and minors, but most students are enrolled to fulfill their Liberal Arts and Sciences Lab science elective. There are no prerequisites for the course. There are no TAs. Inclusion of quantitative content pre-TMYN Students encounter math frequently in this course. Previously, I would typically introduce a calculation in class, have them try it on their own/in groups during class time, and then have a similar calculation as a homework assignment or in lab. For students who had major difficulty with the calculations, I tried to work with them individually during class/lab, encouraged them to work with me outside of class time, and have encouraged some to visit the math help center - but students have reported that the math center is geared toward math classes and not math that is embedded in science classes. Since many of our students have off-campus employment - often full-time - scheduling additional time on campus presents a challenge for them. Incorporating TMYN into this course provides a math resource that can be accessed as a student's schedule allows. Strategies for successfully implementing The Math You Need Students complete the pre-test during the first week of class (delivered online, but completed during class). As an introduction to TMYN, students work through the Density modulein class. Density will be discussed during the following week as it relates to oceanic and continental crust and isostasy. The remainder of the modules (described below) were completed outside of class time, with a deadline immediately prior to their use in class/lab. The first two labs cover seafloor spreading – during the first lab, students calculate spreading rate based on distance from the ridge axis and seafloor age and complete unit conversions (km/Myr to cm/y). The second lab revisits the seafloor spreading data from Lab 1, but students learn to use a spreadsheet to organize and graph data, determine the best fit line, and determine spreading rate from the best fit line. To incorporate TMYN, students will complete Rates and Unit Conversions for Lab 1, and Best Fit Line for Lab 2. The sediments lab (Lab 4) includes rates again (sedimentation rates), but students will need to rearrange the equations to calculate the age of sediment layers based on sedimentation rate and depth. Students will therefore complete the Rearranging Equations Module before Lab 4. During the remainder of the course, students can revisit the above modules (as outlined on the syllabus). Students would benefit from working through the unit conversions and rearranging equations modules two times at a minimum, so I encourage this by allowing them to replace a previous quiz score with one that comes later in the semester. Assessment of their learning is based on pre- and post-test results, as well as quiz scores. The pre-test score does not count for the grade. The module quizzes and post-test are graded and incorporated into their 'Assignments' grade. Reflections and Results (after implementing) Overall, the first year of implementation seemed successful. Students improved their math skills during the course of the semester, as evidenced by the pre- to post-test gain (25% during fall, 10% during spring). Students completed most of the modules early in the semester based on how concepts come up, and they were encouraged to revisit them as necessary later. TMYN was heavily integrated - I mentioned TMYN in class almost every day during the first month, and it appeared in their assignments and labs (e.g., "recall the TMYN rates module that you just completed - use that information to complete the following calculation . . . "). It was mentioned with less frequency later since they had completed most of the modules, but I reminded them about the modules when new calculations were heading their way. This integration established TMYN as the 'culture' of the class, and most students responded favorably based on relatively high participation rates on the modules and improvement in scores. Anecdotally, students also seemed more willing to ask for additional assistance with calculations, and the fear factor was less apparent.

Eighth grade class studying algebra at middle school By Michael Jacobson Starting this fall, eighth graders are solving linear equations like never before at Paynesville Area Middle School. This year, for the first time, one class of eighth graders at PAMS is taking algebra, a subject that traditionally has only been taught at the high school. Todd Spanier, who is in his third year of teaching at PAMS, taught algebra to eighth graders during his five previous years of teaching in Buffalo. Upon coming to PAMS, the Paynesville native noticed that our math curriculum was not as advanced as that used in Buffalo. He immediately wanted to advance the curriculum and add algebra to eighth grade, but the timing wasn't right until this year. With all the rearranging in the schedule at the middle school due to the effects of the budget cuts, Spanier decided he might as well suggest adding an algebra class in the eighth grade. "As long as there's so much change, let's throw something else in there," he thought. The inquisitive algebra class is a teacher's dream, according to Todd Spanier. and has helped other classes. In conferring with administration and the other math teachers, he found support for adding an algebra class in eighth grade. "I'm glad we're finally doing it," said Deb Gillman, the district's curriculum coordinator. "It's something we've wanted to do for several years." Spanier has 26 students in the algebra class this year. Students were identified for the class by standardized test scores, by class performance, and by recommendations from math teachers and aides. Letters were sent to students and their parents, who could opt out of the class. None did, though one student left the district. "My mom thought it'd be good for me," said eighth grader Kristi Louis. Erica Geurts, another eighth grader in the class, wanted to take algebra this year "because everything else would be a big review," she said. Brad Hemmesch, another eighth grader, thinks it's fun to be challenged in algebra. The other math classes are too easy, he said. In seventh grade, the introduction to algebra includes only basic concepts and elementary equations such as a + 2 = 5. Students can solve these equations in their heads (by saying three plus two equals five, so a must be three) without really learning the process of solving an algebraic equation, said Spanier. "They call it an introduction to algebra, but the numbers are so easy (the students) can just use guess and check," he explained. So far in algebra, the students have encountered lots of new concepts, including solving equations with negatives, with fractions, and with variables on both sides. A few weeks ago, Spanier surveyed the students in his algebra class to get their input on how the class was going, whether they were going too fast, etc., and was pleased to find that they were satisfied with the pacing. Spanier loves teaching the class. "It's the ideal class," he said. "It's heaven for a math teacher to have a class like this." "These guys," said Spanier of the algebra class, "they see it once and they get it." The kids have taken to the challenge of learning algebra, asking questions of Spanier in class and during study times. Spanier thinks it's much better to challenge them with new material rather than bore these students with the regular eighth grade math curriculum, which includes a lot of review that they don't need. "They've learned it once and they got it. They don't need another chapter of it, another year of it," he said. And the other eighth grade classes have benefitted, too, Spanier thinks. "When you take 26 kids off the top, you're taking six of the top math kids out of each class. The others have to step it up," he said. The other classes, though they struggled at first, have developed new leaders and have had students who have gained confidence and started to participate in class more. "It's as beneficial for the other classes as it is for the algebra students," Spanier added. "I think both have benefited. I don't see any losers in it." They hoped to find used textbooks for the new algebra class, but could not, so they had to buy another set of new textbooks...the same algebra books as used in the high school. Having algebra in eighth grade should allow students to have more math in high school. In addition to algebra, the high school offers geometry, trigonometry, and analysis. Ultimately, teaching algrebra to eighth graders could pave the way to offering a college-credit math class to seniors, said Spanier. Or it should at least encourage students to take geometry, trigonometry, and analysis in high school, since they now will have four years to take these three classes, rather than having to take a math class every year. For example, if students are in band and choir, noted Spanier, the only way they can take all three math courses is if they don't have a study hall their senior year. This means that next year the eighth graders should be mixed with the current ninth graders in geometry, the next step in the progression of the math curriculum. "I'm hoping these eighth graders will be in there and you won't be able to tell the difference," said Spanier. Geurts, Hemmesch, Louis, and Cary Schlick, another eighth grader, were unanimous in planning to take geometry next year as ninth graders. Spanier sees adding algebra in eighth grade as the first step in improving the math curriculum. He thinks some years two classes of algebra could be added. And if some concepts were added to sixth and seventh grade math, maybe eventually all eighth graders could take algebra. Changing the math curriculum that drastically will have to wait at least until it's the math department's turn in the curriculum cycle again, said Deb Gillman, the district's curriculum coordinator. While the review of the curriculum is coming in the next couple years, the math department's turn to purchase materials - new books, etc. - is three years away.

Peer Review Ratings Overall Rating: This site is a sub collection of a larger set Manipula Math containing a variety of learning material, both textual and visual. It is a self-contained collection of Java Applets that can be used in the teaching and learning of geometry. Please see the related reviews of the main href=" Math with Java site, as well as the following sub-sites: The Manipula Math-Geometry 2 applets are designed to help the user explore the elementary geometry concepts. Target Student Population: Students in a geometry course. Prerequisite Knowledge or Skills: The applets are self-explanatory. Any geometry student can work with these applets. Type of Material: Simulation, animation, and exploration Recommended Uses: These applets could be used as classroom demonstration tools or as aids to students problem solving on homework assignments. Technical Requirements: A "Java-enabled" browser is required. Evaluation and Observation Content Quality Rating: Strengths: Manipula Math-Geometry 2 contains two groups of applets: Circles and Pythagorean Theorem. The groups have 20 and 16 modules, respectively. The applets illustrate the geometry concepts very well, demonstrating the theorems and properties in a simple style. The user will have a more hands on visual knowledge of geometry concepts after exploring with the applets. The applets vary in their approaches. Most involve the moving of a point or rotation of a figure to demonstrate the principle. A few involve watching as the computer demonstrates a proof one step at a time. Many are activities that could be assigned in a laboratory setting or as homework. For many of the applets, the student can decide whether or not to get a hint. The computer will then sketch the key angle, line, or triangle involved in the solution. The diagrams are well structured in that they contain all the necessary information without being cluttered. In particular, there are eight demonstrations of the proof of the Pythagorean Theorem. The Peaucellier Apparatus applet provides a historical perspective as well as activities for the student. This is an excellent and very useful package. Concerns: Occasional grammatical and spelling errors exist. The Pythagorean Theorem applets all include various misspellings: Pythagoriean, Pytharoras, Pythagrean. Shortest Distance has errors in terminology, referring to line BC as side BC. The directions should be restated to, ?The points A to G are vertices?.? Problem of Two Circles (3) does not make the entire conclusion visible when pressing the Next button. Quoits is a good idea but it only shows purple beads on one side. A bead counter would assist this applet. Eye Ball Theorem is a dead link. Potential Effectiveness as a Teaching Tool Rating: Strengths: This site provides a truly excellent teaching tool. The modules are easy to use, have a standard interface, and most come with an explanation section. The activities are exploration based and most can be used without the aid of the instructor. Students can play with the applets to get an intuitive understanding of the geometry concepts and follow-up with a traditional proof. Many of the applets require the student to develop their own conclusion after having manipulated the geometrical objects and are therefore suitable as assignments. These applets will be particularly instructive for the kinesthetic learner. An instructor has the option of selecting from a large variety of visual approaches to the proof of the Pythagorean Theorem. Concerns: Feedback is not provided for some of the applets and the student could develop an incorrect conclusion. Instructor intervention to provide the correct answers and require development of proofs for the conclusions generated is necessary to guarantee that the concepts are correctly mastered. Ease of Use for Both Students and Faculty Rating: Strengths: The applets have controls that are easy to use, clearly labeled, and self-explanatory in function. Hence, the operation of the applets is fairly intuitive. A short explanation section is always found at the beginning of the more complex applets. Available options give the user good control over the appearance of the graphical output of the modules. A single user license is available for use offline. Network/site licenses are available for schools, teachers, and researchers. These licenses allow the purchaser to place the applets on home pages and to make changes to the applets by editing the HTML files. The license may be purchased for the Geometry 2 applets only, or for the Manipula Math Applet Collections, which includes additional applets in Geometry, Trigonometry, Vectors and Calculus. Concerns: No concerns

Like the guys above said, you can think of Linear Algebra is a sort of "sophisticated, ideal form" of an algebraic structure. The study of L.A. focuses on vector spaces. In algebra, you can relax certain axioms of vector spaces and generalize groups, rings, and fields (among other things...). Conversely, you can start with basic group/ring theory and build up by adding axioms to form an algebraic vector space. – JeffAug 23 '12 at 9:08 Adding to other comments: Linear models and multivariate analysis in statistics can be seen as a sort of "advanced linear algebra". I have learnt a lot of linear algebra stuff from appendices to such books! – kjetil b halvorsenSep 22 '12 at 18:52 4 Answers 4 At my [undergraduate] university [which was University of Cincinnati, at the time of this post], the first linear algebra sequence is taught to sophomores. It is mostly computational. Everything takes place in the reals and complex numbers. The class begins with row reducing and culminates with finding determinants and eigenvalues. I don't remember which book we use for this but it's terrible and the class is very easy. Later, students are encouraged to take "abstract" linear algebra, which focuses on abstract vector spaces (though they are all assumed to be over fields of characteristic $0$), inner product spaces, quadratic forms, proving the spectral theorem, and culminates with Jordan canonical form and the theory of convex sets. For this we use Lang's linear algebra. More emphasis is placed on the spectral theorem than anything, with Jordan form and convex sets only if the class moves fast enough so there's time. Finally, after a student has taken the senior level abstract algebra sequence (featuring the basics of groups, rings, and fields), he may elect to take the graduate algebraic structures class, in which module theory, more advanced ring theory, and some representation theory are covered. For this class we use Dummit and Foote (and whichever other books we feel like). [At my incumbent university, University of Florida, basic ring and module theory is done in the first year graduate course, also using Dummit and Foote. Multilinear algebra (tensors) and more advanced ring theory are covered during spring semester of second year graduate algebra, which concurrently uses Lang, Hungerford, and Matsumura.] I have heard that other universities offer graduate courses strictly in advanced linear algebra. An example of a book they may use is Roman, which I have used as a reference many times and I must say I like very much. Different universities will teach different things under the heading "advanced linear algebra", and at different levels. I would suggest you go to a few university websites and see what they have on offer and what the contents are. First of all, it's not clear what an advanced course in linear algebra at either the undergraduate or graduate level consists of. It really depends on what the first course consists of and this varies enormously from university to university depending not only on the background and career paths of the students, but the aims of the instructor. It can be a largely applied course where rigorous theorems about linear transformations and abstract vector spaces are either largely avoided or downplayed, such as those based on Gilbert Strang's textbooks. It can also be a highly abstract course where applications are barely mentioned at all and the fine theoretical structure of finite dimensional vector spaces is developed in full detail, such as Axler's, Halmos' or Hoffman/Kunze's textbooks. And there are textbooks which try to steer a middle course between the 2 extremes, developing both theory and application in more or less equal measure. The classic example of this kind of course is Charles Curtis' textbook. I'm quite sympathetic to the last kind of textbook - finding both the theoretical and applied sides of linear algebra to be of equal importance in developing the subject in it's fullest utility for both mathematicians and scientists. Then again, it's not that cut and dried often, either - often actual courses in linear algebra resist such simple classification - therefore, advanced courses to follow such classes up will be even more difficult to construct. Gilbert Strang's justly famous course at MIT, for example, is a course built around the applications of linear algebra to real world problems. But it's hardly a plug-and-chug, mindless algorithm course: Strang analyzes each application and algorithm, as well as the theory behind it, thoroughly. But at the same time, it's not really an abstract mathematics course the way we describe it-the deep theorems and proofs of linear algebra, while not ignored, are not really the core concerns of the class. For Strang, the abstract theory of linear algebra is really the domain of an abstract algebra course. (Indeed, Strang's course is partially designed to provide a mastery of the computational aspects of linear algebra needed for MIT students to go on to effectively study modern algebra in Micheal Artin's equally famous course!). However, this is MIT we're talking about-hardly your average program with average mathematics majors. In my experience, what most people mean when they say "advanced linear algebra", they mean the abstract theory of linear operators in the context of modern algebra. At most universities, this material is covered in serious abstract algebra courses at either honors undergraduate or first-year graduate level. This means the study of R-modules over commutative rings in the special case where R is a commutative division ring i.e. a field. This means modules, algebras over R, submodules, R-module maps, product spaces, the Jordan-Holder theorem, tensor products, dual spaces, free modules and perhaps some elementary homological algebra. As I've said, this is usually covered in the student's first substantial year-long algebra course, at either the undergraduate or graduate levels. Also in my experience, there usually isn't a separate "advanced linear algebra" class for students at the advanced undergraduate or graduate level. But there are exceptions. For example, Peter Lax's linear algebra book is based on a graduate course on the subject that he's taught there for many years designed to bring incoming graduate students at NYU who are weak in linear algebra up to speed for a second year functional analysis course. Lax became frustrated with the anemic skills in basic linear algebra most graduate students at NYU had and designed this course to rectify this very damaging lacuna in thier training. If you're looking for a text that focuses purely on the abstract theory of linear operators, the best book is probably Module Theory: An Approach To Linear Algebra by T.S. Blythe. THE book on the subject and sadly, out of print and hard to find. Here's to Dover republishing it. +1 for comments on Gilbert Strang's book, I don't know about other books, but I find Insel is good book to start learning Linear Algebra. – RamJan 6 '13 at 3:40 @Ram I like Friedberg,Insel and Spence a great deal-it's extremely well written,careful,comprehensive and has a wealth of applications in addition to careful theory. The problem with this book is that it's TOO comprehensive-unless you assign huge chunks of the book to the students for independent reading,you'll never get through most of the book in a year,let alone one semester! Curtis is a similar book of a much more manageable size. Also, the section on diagonalizable matrices and the Jordan form in Friedberg,et.al is a mess,frankly.The presentation in Curtis is much clearer. – Mathemagician1234Oct 28 '14 at 5:35 To answer your question succinctly, a first course on linear algebra should cover the basic computational tools: row reduction, determinants, and eigenvalues. A more advanced course should force the students to come to terms with more abstract language (vector spaces over an arbitrary field), and it should contain a sophisticated treatment of the spectral theorem. In an ideal world it would also introduce multilinear algebra and/or the canonical forms, but these topics are often reserved for graduate courses (often in the context of rings and modules). In practice there is quite a large gap between advanced undergraduate and graduate algebra. This can lead to strange circumstances wherein students first learn about tensor products in a differential geometry course or the Jordan canonical form in a number theory course. I recommend that undergraduates take as much linear algebra as possible since good graduate programs will often assume that students know more linear algebra than they do in practice.

Algebra Abstract Algebra This book includes over 1500 exercises, many with multiple parts, ranging in scope from routine to fairly sophisticated, and ranging in purpose from basic application of text material to exploration of important theoretical or computational techniques. The structure of the book permits instructors and students to pursue certain areas from their beginnings to an in-depth treatment, or to survey a wider range of areas, seeing how various themes recur and how different structures are related. The emphasis throughout has been to motivate the introduction and development of important algebraic concepts using as many examples as possible.

Developing Mathematics: Probability Through Algebra: Focused on learning mathematics by working problems together, this course explores the fundamental mathematics on a topic that has its roots in secondary level, and is related to the mathematical theme of the Institute. Careful work on this topic allows teachers (and students) to understand exactly how elementary and more advanced procedures in the specific content area are derived and generalize. The course is structured so that each participant can work at his/her own level. Those who are more mathematically advanced may be asked to help those with less preparation. The course is conducted by teacher leaders from the PROMYS program at Boston University. The focus of this strand is entirely on mathematics, although opportunity is provided within the course for reflection on the approach used by the instructors and to consider the implications of such an approach for teaching in secondary classrooms. The topic for the summer is described below: You're at deuce in a tennis game and are 60% likely to win each point. How likely are you to win the game? What is the probability that you roll a sum of 13 when 5 dice are thrown? What is the most likely sum when 5 dice are thrown? Take an expression like x^6+x^5+x^4+x^3+x^2+x and raise it to the fifth power. What do you get? If you raise it to higher and higher powers, what is the distribution of the coefficients "in the long run?" How does the "random" button on your calculator work? What's the probability that two positive integers, chosen at random, have no common factor? And most importantly, what do all these questions have to do with each other? In this three-week course, we'll investigate questions like these (and more). No background in probability or polynomial algebra is assumed, but by the end of three weeks, we promise beautiful mathematical ideas that will make your head spin.

The students learn to check their findings and develop a working acquaintance with all of the principles. They also begin to use letters as variables to indicate patterns and to generate terms and sentences. In addition, Beberman introduces the pupils to using letters as indices to modify a sentence to indicate generalizations, which is discussed in future films. Black and white picture with sound.

You are here Closer and Closer: Introducing Real Analysis Publisher: Jones and Bartlett Number of Pages: 438 Price: 134.95 ISBN: 9780763735937 Closer and Closer is a new textbook for undergraduate real analysis. There is near-universal agreement on what an undergraduate class in real analysis should cover, and the table of contents of this book corresponds to that consensus. Closer and Closer stands out not for its choice of topics but for how those topics are presented. Closer and Closer is divided into two parts: "central ideas" and "excursions." The central ideas are the main theory of the real analysis, while the excursions are common examples and applications. A glance at the table of contents would suggest that the two parts are to be covered sequentially. That is not the intention. The excursions are meant to be covered thoughout the course of the main development. The chapters include pointers directing students to specific excursions once they have sufficient background. Why separate the applications from the main development? This doesn't seem necessary, but there are perhaps a few advantages. First, it may help students distinguish the basic theory from specific examples. Second, it could help instructors decide what material to cut if a course is running out of time. On the other hand, most the material in the excursions is essential. Labeling these topics as "excursions" might imply that they are less important than they actually are. The strength of Closer and Closer is its exposition. Schumacher does a fine job of proving theorems rigorously, but also provides intuitive explanations and motivation. While such exposition is appreciated in any mathematics book, it is especially important in real analysis. A course in real analysis is of course supposed to present the basic results of real analysis. But it also does much more. It teaches students to take intuitive ideas and express them as rigorous mathematical statements. Other courses do the same, but in general it is more difficult to formalize continuous mathematics than discrete mathematics. The history of mathematics bears this out. The material in a rigorous real analysis course represents the conclusion of decades of research and heated debate on the foundations of continuous mathematics. It is especially important in real analysis to explain the correspondence between formal mathematics and intuitive notions. Closer and Closer contains in written form much of the dialog given in lecture by a good instructor but not often committed to paper. Having such good explanations in the textbook may allow an instructor to devote a little more class time to discussion and problem solving. John D. Cook is a research statistician at M. D.

Mathematics is a creative and highly inter-connected problem solving discipline developed over centuries. Through history, mathematics has been essential for solving some of the most intriguing problems and today it is just as necessary for everyday life. Although we now have technological advances to solve many difficult calculations, these are a direct result of mathematical knowledge and the needs for mathematical thinking in science, technology and engineering, demonstrating its power and importance. The mathematics curriculum provides a foundation for understanding and develops reasoning, ability whilst also developing enjoyment and curiosity about the subject. Aims We aim to develop pupils' understanding of key mathematical concepts and processes in order to enable pupils to solve problems using a variety of techniques and skills. This requires pupils to be fluent in the fundamentals of mathematics and to reason mathematically. This is turn happens through repeated practise to increase fluency and mastery, application of skills to familiar and unfamiliar contexts, learning of formulae, application to calculations, analysis and interpretation of mathematical information, as well as contextualising and applying appropriate elements to situations within which pupils are familiar. Areas of study/Subject content Number Algebra Ratio, proportion and rates of change Geometry and measures: learn and apply formulae in order to calculate problems. Probability Statistics Year 7 – All year 7 pupils start secondary mathematics with strong links to STEM (Science Technology Engineering and Mathematics). This enables Pupils to develop a depth of understanding for core operations + - × ÷ with strong links to physical application to support their understanding of core concepts. Key Stage 3 - Throughout Key Stage 3, all pupils study mathematics covering the full spectrum of: Number, Calculating, Algebra, Geometry and Statistics. These sit alongside Mathematical Processes and Applications and Functional mathematics in order to develop independent mathematicians with skills which are transferable to other subject areas. Key Stage 4 - All pupils are studying a Linear GCSE mathematics course set by Edexcel. This is a two year course with two examination papers sat in the summer of Year 11, one of which is a calculator paper and the other a non-calculator paper. These will test the core skills of Number, Algebra, Geometry, Statistics, Probability and Ratio. Courses offered Key stage/year: Qualification: Main topics students study & Main skills students develop: Compulsory Collins Mathematics KS3 National Curriculum Main topics students study: Number Algebra Shape Data Main skills students develop: Our 2 year KS3 course is designed to ensure our pupils have the full tool kit in Mathematics that they need to tackle GCSE. It builds on their numeracy and starts to develop their ability to use and manipulate algebra. It also continues to develop their skills in data handling and shape, space and measure. Functional Mathematics is built into the course and is also the focus of a dedicated lesson every half term. We teach the Edexcel linear course with pupils either following the foundation or higher specification. The foundation course covers a range of topics in Number, Algebra, Shape and Data handling up to C grade. It emphasises pupils ability to use these skills and also be able to apply them to real life problems. The higher course takes these topics further so pupils can tackle more complex problems, as well as giving them the basis they need to use Mathematics beyond GCSE.

Rick Hansen Secondary School 2011-2012 DEPARTMENT: Mathematics CODE: MCR 3U0 COURSE: Functions, Grade 11, University Preparation CREDIT: 1 PREREQUISITE: Principles of Mathematics, Grade 10, Academic TEACHER: Ms. Johal PHONE: (905) 567-4260 x 533 (voicemail) STRONGLY RECOMMENDED PREPARATION: 75% or higher in MPM 2D0 COURSE DESCRIPTION: This course introduces the mathematical concept of the function by extending students' experiences with linear and quadratic relations. Students will investigate properties of discrete and continuous functions, including trigonometric and exponential functions; represent functions numerically, algebraically, and graphically; solve problems involving applications of functions; investigate inverse functions; and develop facility in determining equivalent algebraic expressions. Students will reason mathematically and communicate their thinking as they solve multi-step problems. Throughout this course, students will: • Develop, select, apply, compare, and adapt a variety of problem-solving strategies as they pose and solve problems and conduct investigations, to help deepen their mathematical understanding; • Develop and apply reasoning skills (e.g., use of inductive reasoning, deductive reasoning, and counter- examples; construction of proofs) to make mathematical conjectures, assess conjectures, and justify conclusions, and plan and construct organized mathematical arguments; • Demonstrate that they are reflecting on and monitoring their thinking to help clarify their understanding as they complete an investigation or solve a problem (e.g., by assessing the effectiveness of strategies and processes used, by proposing alternative approaches, by judging the reasonableness of results, by verifying solutions); • Select and use a variety of concrete, visual, and electronic learning tools and appropriate computational strategies to investigate mathematical ideas and to solve problems; • Make connections among mathematical concepts and procedures, and relate mathematical ideas to situations or phenomena drawn from other contexts (e.g., other curriculum areas, daily life, current events, art and culture, sports); • Create a variety of representations of mathematical ideas (e.g., numeric, geometric, algebraic, graphical, pictorial representations; onscreen dynamic representations), connect and compare them, and select and apply the appropriate representations to solve problems; • Communicate mathematical thinking orally, visually, and in writing, using precise mathematical vocabulary and a variety of appropriate representations, and observing mathematical conventions. OVERALL EXPECTATIONS: By the end of this course, students will be able to:  Demonstrate an understanding of a variety of functions (including quadratic, exponential, trigonometric, and discrete functions), identify and represent these functions and their inverses, describe properties of these functions, and make connections between the numerical, algebraic, and graphical representations of these functions using transformations;  Demonstrate an understanding of: expressions containing rational exponents and radicals; recursive sequences and their connection to Pascal's Triangle; trigonometric ratios for angles less than 360 ; 0 periodic relationships and sinusoidal functions;  Solve problems involving functions, including those arising from real-world applications ;  Demonstrate an understanding of arithmetic and geometric sequences and series, make connections to financial applications, and solve related problems (including those involving compound interest and annuities). TECHNOLOGICAL EXPECTATIONS: Information and communication technologies provide a range of tools that can significantly extend, enrich, and support student learning in Mathematics. Technology will be used, where appropriate, to reduce the time spent on routine mathematical tasks, to allow students to devote more of their efforts to thinking and concept understanding and development. For example: 1. Throughout the term, students will be required to access and print material from the course website: myclass.peelschools.org, select Rick Hansen Secondary School from the second drop down menu; find the course code. MCR 3U0 Attia. 2. Students will be provided with instructions to download Virtual TI and Geometers' Sketchpad. This will provide them the opportunity to have access to graphing calculator and dynamic geometry software outside of the classroom. Students' access to these resources is a course expectation, and assignments may require that the student use this software. Students will also be given the opportunity to use this and other software in the classroom. ASSESSMENT & EVALUATION: Assessment and evaluation will be based on provincial curriculum expectations and will incorporate the four categories of the Provincial Achievement Chart with approximately the following weightings: Knowledge & Application Communication Thinking Understanding 23% 30% 17% 30%  tests  problem solving  appropriate use of mathematical  investigations  quizzes  problem posing language & symbols  construction of  assignments  applying  individual or group presentations mathematical models mathematical  journals  problem solving models  portfolios NOTE: On some assessment tasks, students will be graded using a rating scale called a rubric. Based on any of the categories of the Provincial Achievement Chart for Mathematics, a student's work may be rated at a particular level. At some point, these "levels" will be converted to percentage grades using the following conversion table: LEVEL CONVERSIONS: LEVEL % Grade LEVEL % Grade LEVEL % Grade LEVEL % Grade 4++ 95 – 100 3+ 78 2 65 1- 52 4+ 93 3 75 2- 62 R+ 45 4 88 3- 72 1+ 58 R 40 4- 82 2+ 68 1 55 R- 0 - 35 FORMAT OF EVALUATION: During the term, students will have many opportunities to practice the various skills they are learning and may receive feedback in the form of a written comment, a level, or a score. These practice opportunities (called FORMATIVE ASSESSMENTS) are not necessarily counted as part of their final grade. They are intended to provide feedback with respect to how well the student is grasping the concepts being taught. 70% of the students final grade will be based on work that is done throughout the term in class. The work that students complete throughout the term for grading purposes is called SUMMATIVE EVALUATION. In any given unit, overall and specific expectations will be assessed to measure student achievement in the areas of knowledge/understanding, application, communication, and problem solving. The categories assessed will vary with each assessment task, and will carry different weightings depending on the complexity of the task. Students will receive feedback in the form of levels or marks. At the end of the course, students are expected to complete a FINAL SUMMATIVE, worth 30% of their final mark. This summative could take the form of a performance task, an exam, a formal writing piece, or a combination of these. FINAL GRADE: Term Work (70%) + Final Summative Assessment (30%) DEADLINES: 1. Deadlines are set to encourage students to manage their workload and time. Some task deadlines are negotiable; some are absolute. 2. There will be "key assessment tasks" that must be completed by students in order for their teachers to properly determine how well students have grasped the concepts or skills that have been taught in a unit/course. A student who fails to submit one of these tasks may receive a mark of 'zero' if any of the following conditions apply: a) s/he was provided with sufficient or reasonable time to complete the task b) s/he had the opportunity to negotiate an extension with the teacher prior to the deadline c) the assessment has already been marked and returned to the whole class d) the assessment was plagiarized from another person's work Since students must provide sufficient evidence of their learning, incomplete tasks could result in the loss of their credit. It is therefore imperative that all students submit all assigned assessments in order to demonstrate a thorough understanding of course expectations and concepts. 3. It is never acceptable to submit work late without negotiating alternate deadlines. This responsibility will be reflected in the learning skills on the mid-term and final report card. LEARNING SKILLS EXPECTATIONS: It is an expectation that each student is assessed not only on their academic achievement but also on their Learning Skills. These skills include: Responsibility, Organization, Independent Work, Collaboration, Initiative, Self-regulation. Students will have the opportunity to assess themselves and their classmates in these categories in addition to the teacher providing feedback. Students will be provided a rubric, checklist or some other form of feedback sheet when this type of feedback occurs. Note to Student and Parents/Guardians: Please sign below to show that you are aware of the expectations of this course and that you have the name and contact number for your son/daughter's teacher.

Numerical Methods Algorithms and Applications 9780130314000 ISBN: 0130314005 Pub Date: 2002 Publisher: Prentice Hall Summary: The purpose of this text is to present the fundamental numerical techniques used in engineering, applied mathematics, computer science, and the physical and life sciences in a manner that is both interesting and understandable to undergraduate and beginning graduate students in those fields. The organization of the chapters, and of the material within each chapter, is designed with student learning as the primary obj...ective. A detailed algorithm is given for each method presented, so that students can write simple programs implementing the technique in the computer language of their choice. Numerous examples of the use of the methods are also included. The first chapter sets the stage for the material in the rest of the text, giving a brief introduction to the long history of numerical techniques and a "preview of coming attractions" for some of the recurring themes in the remainder of the text. It also presents a summary of the key components of a computer program for solving problems involving numerical techniques such as those given in the text. The trapezoid rule for numerical integration is used to illustrate the relationship between a numerical algorithm and a computer program implementing the algorithm. Sample programs are given in several different languages. Each of the subsequent chapters begins with a one page overview of the subject matter, together with an indication as to how the topics presented in the chapter are related to those in previous and subsequent chapters. Introductory examples are presented to suggest a few of the types of problems for which the topics of the chapter may be used. Following the sections in which the methods are presented, each chapter concludes with a summary of the most important formulas, of suggestions for further reading, and an extensive set of exercises. The first group of problems provides fairly routine practice of the techniques; the second group includes applications adapted from a variety of fields, and the final group of problems encourages students to extend their understanding of either the theoretical or the computational aspects of the methods. The presentation of each numerical technique is based on the successful teaching methodology of providing examples and geometric motivation for a method, and a concise statement of the steps to carry out the computation, before giving a mathematical derivation of the process or a discussion of the more theoretical issues that are relevant to the use and understanding of the topic. Each topic is illustrated by examples that range in complexity from very simple to moderate. Geometrical or graphical illustrations are included whenever they are appropriate. The last section of each chapter gives a brief discussion of more advanced methods for solving the kinds of problems covered in the chapter, including methods used in MATLAB, Mathcad,Mathematica,and various software libraries. The chapters are arranged according to the following general areas: Chapter 2 deals with solving nonlinear equations of a single variable. Chapters 3-6 treat topics from numerical linear algebra. Chapter 7 considers nonlinear functions of several variables Chapters 8-10 cover numerical methods for data interpolation and approximation. Chapter 11 presents numerical differentiation and integration. Chapters 12-15 introduce numerical techniques for solving differential equations. For much of the material, a calculus sequence that includes an introduction to differential equations and linear algebra provides adequate background. For more in-depth coverage of the topics from linear algebra (especially the OR method for eigenvalues), a linear algebra course would be an appropriate prerequisite. The coverage of Fourier approximation and FFT (Chapter 10) and partial differential equations (Chapter 15) assumes that the students have somewhat more mathematical maturity sin Fausett, Laurene V. is the author of Numerical Methods Algorithms and Applications, published 2002 under ISBN 9780130314000 and 0130314005.

Maths calculus Covering all syllabus Ebook PDF download Here is the ebook for calculus: The right way to begin a calculus book is with calculus. This chapter will jump directly into the two problems that the subject was invented to solve. You will see what the questions are, and you will see an important part of the answer. There are plenty of good things left for the other chapters, so why not get started? The book begins with an example that is familiar to everybody who drives a car. It is calculus in action-the driver sees it happening. The example is the relation between the speedometer and the odometer. One measures the speed (or velocity); the other measures the distance traveled. We will write v for the velocity, and f for how far the car has gone. The two instruments sit together on the dashboard: Notice that the units of measurement are different for v and f.The distance f is measured in kilometers or miles (it is easier to say miles). The velocity v is measured in km/hr or miles per hour. A unit of time enters the velocity but not the distance. Every formula to compute v from f will have f divided by time.

Intermediate Algebra: Connecting Concepts through Applications 9780534496364 ISBN: 0534496369 Edition: 1 Pub Date: 2011 Publisher: Brooks Cole Summary: INTERMEDIATE ALGEBRA: CONNECTING CONCEPTS THROUGH APPLICATIONS shows students how to apply traditional mathematical skills in real-world contexts. The emphasis on skill building and applications engages students as they master concepts, problem solving, and communication skills. It modifies the rule of four, integrating algebraic techniques, graphing, the use of data in tables, and writing sentences to communicate so...lutions to application problems. The authors have developed several key ideas to make concepts real and vivid for students. First, the authors integrate applications, drawing on real-world data to show students why they need to know and how to apply math. The applications help students develop the skills needed to explain the meaning of answers in the context of the application. Second, they emphasize strong algebra skills. These skills support the applications and enhance student comprehension. Third, the authors use an eyeball best-fit approach to modeling. Doing models by hand helps students focus on the characteristics of each function type. Fourth, the text underscores the importance of graphs and graphing. Students learn graphing by hand, while the graphing calculator is used to display real-life data problems. In short, INTERMEDIATE ALGEBRA: CONNECTING CONCEPTS THROUGH APPLICATIONS takes an application-driven approach to algebra, using appropriate calculator technology as students master algebraic concepts and skills.

Introduction to Computational Science Introduction to scientific computing, emphasizing basic numerical algorithms and the informed use of mathematical software. Matrix computation, systems of linear equations, differential equations. Students will learn and use the Matlab language. Textbook: The textbook is: Numerical Computing with Matlab, by Cleve Moler. The book has a web site. Besides the bookstore, you can download the book from its web site, or you can order it from SIAM, the Society for Industrial and Applied Mathematics. You can get a discount on the book if you are a member of SIAM, which is free for UCSB students (talk to me). Course software and computer resources: You'll use Matlab for all your programming in the course. It works on the Linux computers in CSIL and on the Windows computers in the ECI labs. To run Matlab from your personal machine, you can log in to CSIL remotely and forward the graphics, or else buy a copy of the "student version" at the bookstore. The course will also use the "NCM" software, which you can put on your Matlab path at CSIL in any of several ways: Homework policy: There will be a homework assignment every week. You may talk to each other about the assignment, but what you submit must be your own work. Most weeks there will be two sets of problems: one to be turned in for a grade, and one for self-study to test your own understanding of the course material. All homework must be submitted in hard copy, on paper. We strongly encourage you to write up your homework using LaTeX, which is the standard markup language for mathematical documents. To get you started, here is the LaTeX for the review quiz. When a homework exercise requires a Matlab program, turn in four things: the Matlab program listing (m-files; use "verbatim" mode in LaTeX) the relevant lines from the diary of your Matlab session running the program ("verbatim" in LaTeX) copies of any output figures or plots (save figures as pdf's and include in LaTeX) a description in English of what you did and how Homework is due every Monday at the beginning of class, or in the CS111 homework box in the Computer Science mailroom, 2108 HFH, by 9:00 am Monday. No late homework will be accepted under any circumstances, but I will drop your two lowest homework grades. If you have questions about grading of homework, talk to the grader or the t.a. first. If you are unable to reach an agreement, make an appointment to talk to me.

Product Details Methods for Euclidean Geometry is a college geometry textbook with a unique mission. Instead of treating the subject as a distinct unit in the math curriculum, the authors integrate a variety of mathematical disciplines to engage and enlighten the reader... --MAA Reviews Methods for Euclidean Geometry explores one of the oldest and most beautiful of mathematical subjects. The book begins with a thorough presentation of classical solution methods for plane geometry problems, but its distinguishing feature is the subsequent collection of methods which have appeared since 1600. For example, the coordinate method, which is a central part of the book, has been part of mathematics for four centuries. However, it has rarely served as a tool that students consider using when faced with geometry problems. The same holds true regarding the use of trigonometry, vectors, complex numbers, and transformations. The book presents each of these as self-contained topics, providing examples of their applications to geometry problems. Both strengths and weaknesses of various methods, as well as the ranges of their effective applications, are discussed. Importance is placed on the problems and their solutions. The book contains numerous problems of varying difficulty; over a third of its contents are devoted to problem statements, hints, and complete solutions. The book can be used as a textbook for geometry courses; as a source book for geometry and other mathematics courses; for capstone, problem-solving, and enrichment courses; and for independent study courses.

GeoGebra 5.0.134.0 GeoGebra is a very useful mathematics tool for education in secondary schools, which brings together geometry, algebra and calculus. GeoGebra is also a dynamic geometry system, meaning you can do constructions with points, segments, vectors, lines, conic sections as well as functions and change them dynamically afterwards. On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum. These two views are characteristic of GeoGebra: an expression in the algebra window corresponds to an object in the geometry window and vice versa. Related Programs

Teaching High School Mathematics; First Course; Verbalizing Generalizations in the Classroom Description: Mathematician Max Beberman teaches students name principles and provides instances to justify shortcuts in arithmetic computations. Beberman emphasizes that a student can use a generalization without having heard it spoken or seen it in print, and he can apply the generalization to solve problems. But, he cannot test his intuitive insight by a deductive proof without first supplementing the insight with a precise linguistic formulation. Also, until he achieves this formulation, the student cannot use an insight as an assumption from which to derive new generalizations. Black and white picture with sound. Kodak edge code reads "square triangle," which correlates to 1965.

We Offer Four Types of Student Programs Overview Catchup Math is for students in grades 7 and above, but our Programs will "drill down" to review material taught in elementary school as necessary. We offer Subject Proficiency Programs, Graduation Test Prep Programs, Chapter-based Programs and Custom (Teacher-Created) Programs. Subject Proficiency (K12 and College) Each Subject Proficiency Program reviews a full subject in six sections. Students advance from section to section by taking diagnostic quizzes and reviewing prescribed lessons (with practice) until a passing quiz score is attained. Our K12 Subject Proficiency Programs are Foundations (arithmetic review), Essentials (covering grades 6-7 Math), Pre-Algebra, Algebra 1, Geometry, and Algebra 2. For colleges, we offer College Basic Math and Elementary Algebra. Teachers may enroll students in specific Proficiency Programs or have them auto-enroll via an online diagnostic placement test. Graduation Test Prep Students may prepare for their high school exit exam with one of our Graduation Test Prep Programs. These programs typically cover the material for a specific state, in eight sections. Students advance from section to section as they demonstrate mastery of the material. Chapter-Based Teachers can assign material based on typical textbook chapter topics. Each of the ten or more chapters within our Chapter-based Programs consists of two sections. Our five Chapter-based subjects are Pre-Algebra, Algebra 1, Geometry, Algebra 2, and Elementary Algebra (for colleges). Customization Faculty may quickly and easily create their own Programs without quizzes by selecting among all the lessons contained within Catchup Math. Built-in Custom Programs for all of the Proficiency Programs are provided for convenience. Also, teachers may create their own custom pre-tests, post-tests, quizzes, and exams by selecting from our complete online question bank. Teachers may also create their own problems for use in assignments using our Custom Problems facility.

Transcript of "Linear algebra with aplications - Steven J. Leon" 2. PREFACE This solutions manual is designed to accompany the seventh edition of Linear Algebra with Applications by Steven J. Leon. The answers in this manual supplement those given in the answer key of the textbook. In addition this manual contains the complete solutions to all of the nonroutine exercises in the book. At the end of each chapter of the textbook there are two chapter tests (A and B) and a section of computer exercises to be solved using MATLAB. The questions in each Chapter Test A are to be answered as either true or false. Although the truefalse answers are given in the Answer Section of the textbook, students are required to explain or prove their answers. This manual includes explanations, proofs, and counterexamples for all Chapter Test A questions. The chapter tests labelled B contain workout problems. The answers to these problems are not given in the Answers to Selected Exercises Section of the textbook, however, they are provided in this manual. Complete solutions are given for all of the nonroutine Chapter Test B exercises. In the MATLAB exercises most of the computations are straightforward. Consequently they have not been included in this solutions manual. On the other hand, the text also includes questions related to the computations. The purpose of the questions is to emphasize the significance of the computations. The solutions manual does provide the answers to most of these questions. There are some questions for which it is not possible to provide a single answer. For example, aome exercises involve randomly generated matrices. In these cases the answers may depend on the particular random matrices that were generated. Steven J. Leon sleon@umassd.edu 5. 2 CHAPTER 1 (a) If m1 = m2 , then one can solve the second equation for x1 x1 = b2 − b1 m1 − m2 One can then plug this value of x1 into the first equation and solve for x2 . Thus, if m1 = m2 , there will be a unique ordered pair (x1, x2) that satisfies the two equations. (b) If m1 = m2 , then the x1 term drops out in the second equation 0 = b2 − b1 This is possible if and only if b1 = b2. (c) If m1 = m2 , then the two equations represent lines in the plane with different slopes. Two nonparallel lines intersect in a point. That point will be the unique solution to the system. If m1 = m2 and b1 = b2 , then both equations represent the same line and consequently every point on that line will satisfy both equations. If m1 = m2 and b1 = b2 , then the equations represent parallel lines. Since parallel lines do not intersect, there is no point on both lines and hence no solution to the system. 10. The system must be consistent since (0, 0) is a solution. 11. A linear equation in 3 unknowns represents a plane in three space. The solution set to a 3 × 3 linear system would be the set of all points that lie on all three planes. If the planes are parallel or one plane is parallel to the line of intersection of the other two, then the solution set will be empty. The three equations could represent the same plane or the three planes could all intersect in a line. In either case the solution set will contain infinitely many points. If the three planes intersect in a point then the solution set will contain only that point. SECTION 2 2. (b) The system is consistent with a unique solution (4, −1). 4. (b) x1 and x3 are lead variables and x2 is a free variable. (d) x1 and x3 are lead variables and x2 and x4 are free variables. (f) x2 and x3 are lead variables and x1 is a free variable. 5. (l) The solution is (0, −1.5, −3.5). 6. (c) The solution set consists of all ordered triples of the form (0, −α, α). 7. A homogeneous linear equation in 3 unknowns corresponds to a plane that passes through the origin in 3-space. Two such equations would correspond to two planes through the origin. If one equation is a multiple of the other, then both represent the same plane through the origin and every point on that plane will be a solution to the system. If one equation is not a multiple of the other, then we have two distinct planes that intersect in a line through the origin. Every point on the line of intersection will be a solution to the linear system. So in either case the system must have infinitely many solutions. 6. Section 3 3 In the case of a nonhomogeneous 2 × 3 linear system, the equations correspond to planes that do not both pass through the origin. If one equation is a multiple of the other, then both represent the same plane and there are infinitely many solutions. If the equations represent planes that are parallel, then they do not intersect and hence the system will not have any solutions. If the equations represent distinct planes that are not parallel, then they must intersect in a line and hence there will be infinitely many solutions. So the only possibilities for a nonhomogeneous 2 × 3 linear system are 0 or infinitely many solutions. 9. (a) Since the system is homogeneous it must be consistent. 14. At each intersection the number of vehicles entering must equal the number of vehicles leaving in order for the traffic to flow. This condition leads to the following system of equations x1 + a1 = x2 + b1 x2 + a2 = x3 + b2 x3 + a3 = x4 + b3 x4 + a4 = x1 + b4 If we add all four equations we get x1 + x2 + x3 + x4 + a1 + a2 + a3 + a4 = x1 + x2 + x3 + x4 + b1 + b2 + b3 + b4 and hence a1 + a2 + a3 + a4 = b1 + b2 + b3 + b4 15. If (c1 , c2) is a solution, then a11c1 + a12c2 = 0 a21c1 + a22c2 = 0 Multiplying both equations through by α, one obtains a11(αc1) + a12(αc2 ) = α · 0 = 0 a21(αc1) + a22(αc2 ) = α · 0 = 0 Thus (αc1, αc2) is also a solution. 16. (a) If x4 = 0 then x1 , x2 , and x3 will all be 0. Thus if no glucose is produced then there is no reaction. (0, 0, 0, 0) is the trivial solution in the sense that if there are no molecules of carbon dioxide and water, then there will be no reaction. (b) If we choose another value of x4, say x4 = 2, then we end up with solution x1 = 12, x2 = 12, x3 = 12, x4 = 2. Note the ratios are still 6:6:6:1. SECTION 3     1. (e)    8 0 −1 −15 −4 −6 11 −3 6        15. 12 CHAPTER 1 Therefore tjj = ujj rjj j = 1, . . . , n T 15. If we set x = (2, 1 − 4) , then Ax = 2a1 + 1a2 − 4a3 = 0 Thus x is a nonzero solution to the system Ax = 0. But if a homogeneous system has a nonzero solution, then it must have infinitely many solutions. In particular, if c is any scalar, then cx is also a solution to the system since A(cx) = cAx = c0 = 0 Since Ax = 0 and x = 0 it follows that the matrix A must be singular. (See Theorem 1.4.2) 16. If a1 = 3a2 − 2a3, then a1 − 3a2 + 2a3 = 0 Therefore x = (1, −3, 2)T is a nontrivial solution to Ax = 0. It follows form Theorem 1.4.2 that A must be singular. 17. If x0 = 0 and Ax0 = Bx0 , then Cx0 = 0 and it follows from Theorem 1.4.2 that C must be singular. 18. If B is singular, then it follows from Theorem 1.4.2 that there exists a nonzero vector x such that Bx = 0. If C = AB, then Cx = ABx = A0 = 0 Thus, by Theorem 1.4.2, C must also be singular. 19. (a) If U is upper triangular with nonzero diagonal entries, then using row operation II, U can be transformed into an upper triangular matrix with 1's on the diagonal. Row operation III can then be used to eliminate all of the entries above the diagonal. Thus U is row equivalent to I and hence is nonsingular. (b) The same row operations that were used to reduce U to the identity matrix will transform I into U −1. Row operation II applied to I will just change the values of the diagonal entries. When the row operation III steps referred to in part (a) are applied to a diagonal matrix, the entries above the diagonal are filled in. The resulting matrix, U −1, will be upper triangular. 20. Since A is nonsingular it is row equivalent to I. Hence there exist elementary matrices E1, E2, . . . , Ek such that Ek · · · E1 A = I It follows that A−1 = Ek · · · E1 and Ek · · · E1 B = A−1B = C The same row operations that reduce A to I, will transform B to C. Therefore the reduced row echelon form of (A | B) will be (I | C). 16. Section 4 13 21. (a) If the diagonal entries of D1 are α1 , α2, . . . , αn and the diagonal entries of D2 are β1 , β2, . . . , βn , then D1 D2 will be a diagonal matrix with diagonal entries α1β1 , α2β2 , . . . , αnβn and D2 D1 will be a diagonal matrix with diagonal entries β1 α1, β2α2 , . . ., βn αn. Since the two have the same diagonal entries it follows that D1 D2 = D2 D1 . (b) AB = A(a0 I + a1A + · · · + ak Ak ) = a0A + a1 A2 + · · · + ak Ak+1 = (a0I + a1A + · · · + ak Ak )A = BA 22. If A is symmetric and nonsingular, then (A−1)T = (A−1 )T (AA−1 ) = ((A−1 )TAT )A−1 = A−1 23. If A is row equivalent to B then there exist elementary matrices E1, E2, . . . , Ek such that A = Ek Ek−1 · · · E1B −1 Each of the Ei 's is invertible and Ei is also an elementary matrix (Theorem 1.4.1). Thus −1 −1 −1 B = E1 E2 · · · Ek A and hence B is row equivalent to A. 24. (a) If A is row equivalent to B, then there exist elementary matrices E1 , E2, . . . , Ek such that A = Ek Ek−1 · · · E1B Since B is row equivalent to C, there exist elementary matrices H1, H2, . . ., Hj such that B = Hj Hj−1 · · · H1C Thus A = Ek Ek−1 · · · E1Hj Hj−1 · · · H1C and hence A is row equivalent to C. (b) If A and B are nonsingular n × n matrices then A and B are row equivalent to I. Since A is row equivalent to I and I is row equivalent to B it follows from part (a) that A is row equivalent to B. 25. If U is any row echelon form of A then A can be reduced to U using row operations, so A is row equivalent to U . If B is row equivalent to A then it follows from the result in Exercise 24(a) that B is row equivalent to U . 26. If B is row equivalent to A, then there exist elementary matrices E1, E2, . . ., Ek such that B = Ek Ek−1 · · · E1A Let M = Ek Ek−1 · · · E1 . The matrix M is nonsingular since each of the Ei's is nonsingular. 22. MATLAB Exercises 19 (c) If D = B + C, then AD = AB + AC = O + AC = AC 4. By construction B is upper triangular whose diagonal entries are all equal to 1. Thus B is row equivalent to I and hence B is nonsingular. If one changes B by setting b10,1 = −1/256 and computes Bx, the result is the zero vector. Since x = 0, the matrix B must be singular. 5. (a) Since A is nonsingular its reduced row echelon form is I. If E1, . . . , Ek are elementary matrices such that Ek · · · E1 A = I, then these same matrices can be used to transform (A b) to its reduced row echelon form U . It follows then that U = Ek · · · E1 (A b) = A−1 (A b) = (I A−1 b) Thus, the last column of U should be equal to the solution x of the system Ax = b. (b) After the third column of A is changed, the new matrix A is now singular. Examining the last row of the reduced row echelon form of the augmented matrix (A b), we see that the system is inconsistent. (c) The system Ax = c is consistent since y is a solution. There is a free variable x3, so the system will have infinitely many solutions. (f) The vector v is a solution since Av = A(w + 3z) = Aw + 3Az = c 6. 8. 9. 10. For this solution the free variable x3 = v3 = 3. To determine the general solution just set x = w + tz. This will give the solution corresponding to x3 = t for any real number t. (c) There will be no walks of even length from Vi to Vj whenever i + j is odd. (d) There will be no walks of length k from Vi to Vj whenever i + j + k is odd. (e) The conjecture is still valid for the graph containing the additional edges. (f) If the edge {V6 , V8} is included, then the conjecture is no longer valid. There is now a walk of length 1 V6 to V8 and i + j + k = 6 + 8 + 1 is odd. The change in part (b) should not have a significant effect on the survival potential for the turtles. The change in part (c) will effect the (2, 2) and (3, 2) of the Leslie matrix. The new values for these entries will be l22 = 0.9540 and l32 = 0.0101. With these values the Leslie population model should predict that the survival period will double but the turtles will still eventually die out. (b) x1 = c − V x2.

If A is nonsingular and AB = AC, then we can multiply both sides of the equation by A−1 and conclude that B = C. However, if A is singular, then it is possible to have AB = AC and B = C. For example, if       1 1 , B = 1 1, C = 2 2     A=       1 1 4 4 3 3 then  1 AB =   1  1 AC =   1  11   1 4  12   1 3   1 5 =   4 5   2 5 =   3 5  5   5  5   5 8. The statement is false. An elementary matrix is a matrix that is constructed by performing exactly one elementary row operation on the identity matrix. The product of two elementary matrices will be a matrix formed by performing two elementary row operations on the identity matrix. For example,     1 0 0 1 0 0         E1 =  2 1 0  and E2 =  0 1 0          0 0 1 3 0 1 are elementary matrices, however,   1 0 0     E1E2 =  2 1 0      3 0 1 is not an elementary matrix. 9. The statement is true. The row vectors of A are x1yT , x2yT , . . . , xnyT . Note, all of the row vectors are multiples of yT . Since x and y are nonzero vectors, at least one of these row vectors must be nonzero. However, if any nonzero row is picked as a pivot row, then since all of the other rows are multiples of the pivot row, they will all be eliminated in the first step of the reduction process. The resulting row echelon form will have exactly one nonzero row. 10. The statement is true. If b = a1 + a2 + a3 , then x = (1, 1, 1)T is a solution to Ax = b, since Ax = x1 a1 + x2a2 + x3a3 = a1 + a2 + a3 = b If a2 = a3, then we can also express b as a linear combination b = a1 + 0a2 + 2a3 Thus y = (1, 0, 2)T is also a solution to the system. However, if there is more than one solution, then the echelon form of A must involve a free variable. A consistent system with a free variable must have infinitely many solutions. 26.

If we set x2 = a and x4 = b, then x1 = 4 + a + 7b and x3 = −1 − 3b and hence the solution set consists of all vectors of the form    4 + a + 7b        a   x=  −1 − 3b         b 2. (a) A linear equation in 3 unknowns corresponds to a plane in 3-space. (b) Given 2 equations in 3 unknowns, each equation corresponds to a plane. If one equation is a multiple of the other then the equations represent the same plane and any point on the that plane will be a solution to the system. If the two planes are distinct then they are either parallel or they intersect in a line. If they are parallel they do not intersect, so the system will have no solutions. If they intersect in a line then there will be infinitely many solutions. (c) A homogeneous linear system is always consistent since it has the trivial solution x = 0. It follows from part (b) then that a homogeneous system of 2 equations in 3 unknowns must have infinitely many solutions. Geometrically the 2 equations represent planes that both pass through the origin, so if the planes are distinct they must intersect in a line. 3. (a) If the system is consistent and there are two distinct solutions there must be a free variable and hence there must be infinitely many solutions. In fact all vectors of the form x = x1 + c(x1 − x2) will be solutions since Ax = Ax1 + c(Ax1 − Ax2 ) = b + c(b − b) = b (b) If we set z = x1 − x2 then z = 0 and Az = 0. Therefore it follows from Theorem 1.4.2 that A must be singular. 4. (a) The system will be consistent if and only if the vector b = (3, 1)T can be written as a linear combination of the column vectors of A. Linear combinations of the column vectors of A are vectors of the form        α   + c2  β  = (c1 α + c2β)  1      c1       2α 2β 2 Since b is not a multiple of (1, 2)T the system must be inconsistent. 27. 24 Chapter 1 (b) To obtain a consistent system choose b to be a multiple of (1, 2)T . If this is done the second row of the augmented matrix will zero out in the elimination process and you will end up with one equation in 2 unknowns. The reduced system will have infinitely many solutions. 5. (a) To transform A to B you need to interchange the second and third rows of A. The elementary matrix that does this is   1 0 0     E = 0 0 1     0 1 0 (b) To transform A to C using a column operation you need to subtract twice the second column of A from the first column. The elementary matrix that does this is    1 0 0     F =  −2 1 0      0 0 1 6. If b = 3a1 + a2 + 4a3 then b is a linear combination of the column vectors of A and it follows from the consistency theorem that the system Ax = b is consistent. In fact x = (3, 1, 4)T is a solution to the system. 7. If a1 − 3a2 + 2a3 = 0 then x = (1, −3, 2)T is a solution to Ax = 0. It follows from Theorem 1.4.2 that A must be singular. 8.

If E and F are elementary matrices then they are both nonsingular and their inverses are elementary matrices of the same type.

(a) The column partition of A and the row partition of B must match up, so k must be equal to 5. There is really no restriction on r, it can be any integer in the range 1 ≤ r ≤ 9. In fact r = 10 will work when B has block structure    B11      B21 (b) The (2,2) block of the product is given by A21B12 + A22 B22 29. Chapter 2 SECTION 1 1. (c) det(A) = −3 7. Given that a11 = 0 and a21 = 0, let us interchange the first two rows of A and also multiply the third row through by −a21. We end up with the matrix   a22 a23   a21      0 a12 a13      −a21 a31 −a21 a32 −a21a33 Now if we add a31 times the first row to the third, we obtain the matrix   a22 a23  a21     0    a12 a13     0 a31a22 − a21a32 a31a23 − a21a33 This matrix will be row equivalent to I if and only if a12 a31a22 − a21a32 a13 a31a23 − a21a33 =0 Thus the original matrix A will be row equivalent to I if and only if a12a31a23 − a12a21a33 − a13a31a22 + a13a21a32 = 0 8. Theorem 2.1.3. If A is an n × n triangular matrix then the determinant of A equals the product of the diagonal elements of A. Proof: The proof is by induction on n. In the case n = 1, A = (a11) and det(A) = a11. Assume the result holds for all k × k triangular matrices and 26 32. Section 2 29 SECTION 2 5. To transform the matrix A into the matrix αA one must perform row operation II n times. Each time row operation II is performed the value of the determinant is changed by a factor of α. Thus det(αA) = αn det(A) Alternatively, one can show this result holds by noting that det(αI) is equal to the product of its diagonal entries. Thus, det(αI) = αn and it follows that det(αA) = det(αIA) = det(αI) det(A) = αn det(A) 6. Since det(A−1 ) det(A) = det(A−1 A) = det(I) = 1 it follows that det(A−1 ) = 1 det(A) 8. If E is an elementary matrix of type I or II then E is symmetric, so E T = E. If E is an elementary matrix of type III formed from the identity matrix by adding c times its ith row to its jth row, then E T will be the elementary matrix of type III formed from the identity matrix by adding c times its jth row to its ith row 9. (b) 18; (d) −6; (f) −3 10. Row operation III has no effect on the value of the determinant. Thus if B can be obtained from A using only row operation III, then det(B) = det(A). Row operation I has the effect of changing the sign of the determinant. If B is obtained from A using only row operations I and III, then det(B) = det(A) if row operation I has been applied an even number of times and det(B) = − det(A) if row operation I has been applied an odd number of times. 11. Since det(A2 ) = det(A)2 it follows that det(A2 ) must be a nonnegative real number. (We are assuming the entries of A are all real numbers.) If A2 + I = O then A2 = −I and hence det(A2 ) = det(−I). This is not possible if n is odd, since for n odd, det(−I) = −1. On the other hand it is possible for A2 + I = O when n is even. For example when n = 2, if we take    0 1   A=  −1 0 then it is easily verified that A2 + I = O. 12. (a) Row operation III has no effect on the value of the determinant. Thus 1 det(V ) = x1 x2 1 1 x2 x2 2 1 x3 x2 3 1 = x1 x2 1 0 x2 − x1 x2 − x2 2 1 0 x3 − x1 x2 − x2 3 1 36. MATLAB Exercises 33 Also adj A−1 = det(A−1 )(A−1 )−1 = det(A−1 )A 11. If A = O then adj A is also the zero matrix and hence is singular. If A is singular and A = O then A adj A = det(A)I = 0I = O If aT is any nonzero row vector of A then aT adj A = 0T or (adj A)T a = 0 By Theorem 1.4.2, (adj A)T is singular. Since det(adj A) = det[(adj A)T ] = 0 it follows that adj A is singular. 12. If det(A) = 1 then adj A = det(A)A−1 = A−1 and hence adj(adj A) = adj(A−1 ) It follows from Exercise 10 that adj(adj A) = det(A−1 )A = 1 A=A det(A) 13. The (j, i) entry of QT is qij . Since Q−1 = 1 adj Q det(Q) its (j, i) entry is Qij / det(Q). If Q−1 = QT , then qij = Qij det(Q) MATLAB EXERCISES 2. The magic squares generated by MATLAB have the property that they are nonsingular when n is odd and singular when n is even. 3. (a) The matrix B is formed by interchanging the first two rows of A. det(B) = − det(A). (b) The matrix C is formed by multiplying the third row of A by 4. det(C) = 4 det(A). (c) The matrix D is formed from A by adding 4 times the fourth row of A to the fifth row. det(D) = det(A). 37. 34 Chapter 2 5. The matrix U is very ill-conditioned. In fact it is singular with respect to the machine precision used by MATLAB. So in general one could not expect to get even a single digit of accuracy in the computed values of det(U T ) and det(U U T ). On the other hand, since U is upper triangular, the computed value of det(U ) is the product of its diagonal entries. This value should be accurate to the machine precision. 6. (a) Since Ax = 0 and x = 0, the matrix must be singular. However, there may be no indication of this if the computations are done in floating point arithmetic. To compute the determinant MATLAB does Gaussian elimination to reduce the matrix to upper triangular form U and then multiplies the diagonal entries of U . In this case the product u11u22u33u44u55 has magnitude on the order of 1014. If the computed value of u66 has magnitude of the order 10−k and k ≤ 14, then MATLAB will round the result to a nonzero integer. (MATLAB knows that if you started with an integer matrix, you should end up with an integer value for the determinant.) In general if the determinant is computed in floating point arithmetic, then you cannot expect it to be a reliable indicator of whether or not a matrix is nonsingular. (c) Since A is singular, B = AAT should also be singular. Hence the exact value of det(B) should be 0. CHAPTER TEST A 1. The statement is true since det(AB) = det(A) det(B) = det(B) det(A) = det(BA) 2. The statement is false in general. For example, if    1 0 0   A= and B=   0 0 0  0   1 then det(A + B) = det(I) = 1 while det(A) + det(B) = 0 + 0 = 0. 3. The statement is false in general. For example, if A = I, (the 2 × 2 identity matrix), then det(2A) = 4 while 2 det(A) = 2. 4. The statement is true. For any matrix C, det(C T ) = det(C), so in particular for C = AB we have det((AB)T ) = det(AB) = det(A) det(B) 5. The statement is false in general. For example if    2 3 1   A= and B=   0 4 0  0   8 then det(A) = det(B) = 8, however, A = B. 6. The statement is true. For a product of two matrices we know that det(AB) = det(A) det(B) 54. Section 6 51 is a basis for the row space. Since the reduced row echelon form of the matrix involves one free variable the nullspace will have dimension 1. Setting the free variable x4 = 1 we get x1 = 10/7, x2 = 2/7, x3 = 0 Thus {(10/7, 2/7, 0, 1)T } is a basis for the nullspace. The dimension of the column space equals the rank of the matrix which is 3. Thus the column space must be R3 and we can take as our basis the standard basis {e1 , e2, e3}. (c) The reduced row echelon form of the matrix is   0 0 −0.65   1    0   1 0 1.05      0 0 1 0.75 The set {(1, 0, 0, −0.65), (0, 1, 0, 1.05), (0, 0, 1, 0, 0.75)} is a basis for the row space. The set {(0.65, −1.05, −0.75, 1)T } is a basis for the nullspace. As in part (b) the column space is R3 and we can take {e1 , e2 , e3 } as our basis. 3 (b) The reduced row echelon form of A is given by   2 0 5 −3 0 1     0 1 −1 2 0 U = 0     0 0 0 0 0 1 The lead variables correspond to columns 1, 3, and 6. Thus a1 , a3 , a6 form a basis for the column space of A. The remaining column vectors satisfy the following dependency relationships. a2 = 2a1 a4 = 5a1 − a3 a5 = −3a1 + 2a3 4. (c) consistent, (d) inconsistent, (f) consistent 6. There will be exactly one solution. The condition that b is in the column space of A guarantees that the system is consistent. If the column vectors are linearly independent, then there is at most one solution. Thus the two conditions together imply exactly one solution. 7. (a) Since N (A) = {0} Ax = x1a1 + · · · + xnan = 0 has only the trivial solution x = 0, and hence a1 , . . . , an are linearly independent. The column vectors cannot span Rm since there are only n vectors and n < m. (b) If b is not in the column space of A, then the system must be inconsistent and hence there will be no solutions. If b is in the column space of A, then the system will be consistent, so there will be at least one solution. By part (a), the column vectors are linearly independent, so there cannot 56. Section 6 53 then c1Ax1 + c2 Ax2 + c3 Ax3 = 0 A(c1 x1 + c2 x2 + c3 x3 ) = 0 and it follows that c1 x1 + c2x2 + c3 x3 is in N (A). However, we know from part (a) that N (A) = {0}. Therefore c1x1 + c2 x2 + c3 x3 = 0 Since x1 , x2 , x3 are linearly independent it follows that c1 = c2 = c3 = 0 and hence y1, y2, y3 are linearly independent. (c) Since dim R5 = 5 it takes 5 linearly independent vectors to span the vector space. The vectors y1 , y2, y3 do not span R5 and hence cannot form a basis for R5. 14. Given A is m × n with rank n and y = Ax where x = 0. If y = 0 then x 1 a1 + x 2 a2 + · · · + x n an = 0 But this would imply that the columns vectors of A are linearly dependent. Since A has rank n we know that its column vectors must be linearly independent. Therefore y cannot be equal to 0. 15. If the system Ax = b is consistent, then b is in the column space of A. Therefore the column space of (A | b) will equal the column space of A. Since the rank of a matrix is equal to the dimension of the column space it follows that the rank of (A | b) equals the rank of A. Conversely if (A | b) and A have the same rank, then b must be in the column space of A. If b were not in the column space of A, then the rank of (A | b) would equal rank(A) + 1. 16. (a) If x ∈ N (A), then BAx = B0 = 0 and hence x ∈ N (BA). Thus N (A) is a subspace of N (BA). On the other hand, if x ∈ N (BA), then B(Ax) = BAx = 0 and hence Ax ∈ N (B). But N (B) = {0} since B is nonsingular. Therefore Ax = 0 and hence x ∈ N (A). Thus BA and A have the same nullspace. It follows from the Rank-Nullity Theorem that rank(A) = n − dim N (A) = n − dim N (BA) = rank(BA) (b) By part (a), left multiplication by a nonsingular matrix does not alter the rank. Thus rank(A) = rank(AT ) = rank(C T AT ) = rank((AC)T ) = rank(AC) 57. 54 Chapter 3 17. Corollary 3.6.4. An n×n matrix A is nonsingular if and only if the column vectors of A form a basis for Rn . Proof: It follows from Theorem 3.6.3 that the column vectors of A form a basis for Rn if and only if for each b ∈ Rn the system Ax = b has a unique solution. We claim Ax = b has a unique solution for each b ∈ Rn if and only if A is nonsingular. If A is nonsingular then x = A−1b is the unique solution to Ax = b. Conversely, if for each b ∈ Rn , Ax = b has a unique solution, then x = 0 is the only solution to Ax = 0. Thus it follows from Theorem 1.4.2 that A is nonsingular. 18. If N (A − B) = Rn then the nullity of A − B is n and consequently the rank of A − B must be 0. Therefore A−B = O A = B 19. (a) The column space of B will be a subspace of N (A) if and only if Abj = 0 for j = 1, . . ., n However, the jth column of AB is ABej = Abj , j = 1, . . . , n Thus the column space of B will be a subspace of N (A) if and only if all the column vectors of AB are 0 or equivalently AB = O. (b) Suppose that A has rank r and B has rank k and AB = O. By part (a) the column space of B is a subspace of N (A). Since N (A) has dimension n − r, it follows that the dimension of the column space of B must be less than or equal to n − r. Therefore rank(A) + rank(B) = r + k ≤ r + (n − r) = n 20. Let x0 be a particular solution to Ax = b. If y = x0 + z, where z ∈ N (A), then Ay = Ax0 + Az = b + 0 = b and hence y is also a solution. Conversely, if x0 and y are both solutions to Ax = b and z = y − x0 , then Az = Ay − Ax0 = b − b = 0 and hence z ∈ N (A). 21. (a) Since    T   x1   x1 y      T   x    2   T  x2 y    y =   T       A = xy =  .  .     .   .   .   .         T xm xm y the rows of A are all multiples of yT . Thus {yT } is a basis for the row space of A. Since A = xyT = x(y1 , y2, . . . , yn) 58. Section 6 55 = (y1 x, y2x, . . . , yn x) it follows that the columns of A are all multiples of x and hence {x} is a basis for the column space of A. (b) Since A has rank 1, the nullity of A is n − 1. 22. (a) If c is a vector in the column space of C, then c = ABx for some x ∈ Rr . Let y = Bx. Since c = Ay, it follows that c is in the column space of A and hence the column space of C is a subspace of the column space of A. (b) If cT is a row vector of C, then c is in the column space of C T . But C T = B TAT . Thus, by part (a), c must be in the column space of B T and hence cT must be in the row space of B. (c) It follows from part (a) that rank(C) ≤ rank(A) and it follows from part (b) that rank(C) ≤ rank(B). Therefore rank(C) ≤ min{rank(A), rank(B)} 23 (a) In general a matrix E will have linearly independent column vectors if and only if Ex = 0 has only the trivial solution x = 0. To show that C has linearly independent column vectors we will show that Cx = 0 for all x = 0 and hence that Cx = 0 has only the trivial solution. Let x be any nonzero vector in Rr and let y = Bx. Since B has linearly independent column vectors it follows that y = 0. Similarly since A has linearly independent column vectors, Ay = 0. Thus Cx = ABx = Ay = 0 (b) If A and B both have linearly independent row vectors, then B T and AT both have linearly independent column vectors. Since C T = B TAT , it follows from part (a) that the column vectors of C T are linearly independent, and hence the row vectors of C must be linearly independent. 24. (a) If the column vectors of B are linearly dependent then Bx = 0 for some nonzero vector x ∈ Rr . Thus Cx = ABx = A0 = 0 and hence the column vectors of C must be linearly dependent. (b) If the row vectors of A are linearly dependent then the column vectors of AT must be linearly dependent. Since C T = B T AT , it follows from part (a) that the column vectors of C T must be linearly dependent. If the column vectors of C T are linearly dependent, then the row vectors of C must be linearly dependent. 25. (a) Let C denote the right inverse of A and let b ∈ Rm . If we set x = Cb then Ax = ACb = Im b = b Thus if A has a right inverse then Ax = b will be consistent for each b ∈ Rm and consequently the column vectors of A will span Rm . 59. 56 Chapter 3 (b) No set of less than m vectors can span Rm . Thus if n < m, then the column vectors of A cannot span Rm and consequently A cannot have a right inverse. If n ≥ m then a right inverse is possible. 27. Let B be an n × m matrix. Since DB = Im if and only if T B TDT = Im = Im it follows that D is a left inverse for B if and only if DT is a right inverse for B T . 28. If the column vectors of B are linearly independent, then the row vectors of B T are linearly independent. Thus B T has rank m and consequently the column space of B T is Rm . By Exercise 26, B T has a right inverse and consequently B must have a left inverse. 29. Let B be an n × m matrix. If B has a left inverse, then B T has a right inverse. It follows from Exercise 25 that the column vectors of B T span Rm . Thus the rank of B T is m. The rank of B must also be m and consequently the column vectors of B must be linearly independent. 30. Let u(1, :), u(2, :), . . ., u(k, :) be the nonzero row vectors of U . If c1 u(1, :) + c2 u(2, :) + · · · + ck u(k, :) = 0T then we claim c1 = c2 = · · · = ck = 0 This is true since the leading nonzero entry in u(i, :) is the only nonzero entry in its column. Let us refer to the column containing the leading nonzero entry of u(i, :) as j(i). Thus if yT = c1u(1, :) + c2 u(2, :) + · · · + ck u(k, :) = 0T then 0 = yj(i) = ci , i = 1, . . . , k and it follows that the nonzero row vectors of U are linearly independent. MATLAB EXERCISES 1. (a) The column vectors of U will be linearly independent if and only if the rank of U is 4. (d) The matrices S and T should be inverses. 2. (a) Since r = dim of row space ≤ m and r = dim of column space ≤ n 60. MATLAB Exercises 57 it follows that r ≤ min(m, n) (c) All the rows of A are multiples of yT and all of the columns of A are multiples of x. Thus the rank of A is 1. (d) Since X and Y T were generated randomly, both should have rank 2 and consequently we would expect that their product should also have rank 2. 3. (a) The column space of C is a subspace of the column space of B. Thus A and B must have the same column space and hence the same rank. Therefore we would expect the rank of A to be 4. (b) The first four columns of A should be linearly independent and hence should form a basis for the column space of A. The first four columns of the reduced row echelon form of A should be the same as the first four columns of the 8 × 8 identity matrix. Since the rank is 4, the last four rows should consist entirely of 0's. (c) If U is the reduced row echelon form of B, then U = M B where M is a product of elementary matrices. If B is an n × n matrix of rank n, then U = I and M = B −1 . In this case it follows that the reduced row echelon form of (B BX) will be B −1 (B BX) = (I X) If B is m × n of rank n and n < m, then its reduced row echelon form is given by   I  U = MB =     O It follows that the reduced row echelon form of (B BX) will be     X I  I  M B(I X) =   (I X) =      O O O 4. (d) The vectors Cy and b + cu are equal since Cy = (A + uvT )y = Ay + cu = b + cu The vectors Cz and (1 + d)u are equal since Cz = (A + uvT )z = Az + du = u + du It follows that Cx = C(y − ez) = b + cu − e(1 + d)u = b The rank one update method will fail if d = −1. In this case Cz = (1 + d)u = 0 Since z is nonzero, the matrix C must be singular.

was one of the first books on the Theory of InventiveProblem Solving to appear in the U.S. It quickly became known as the best TRIZ primer available in English—a distinction that it maintains today, nine years after it was first published.Dr. Kaplan's straightforward explanation of the basic elements of TRIZ theory, and hisdescription of the tools that emerged from the first three decades of TRIZ development, arerelevant for experienced engineers and novices alike. His analogy between the search for aninventive solution and the process of solving a quadratic equation is both simple and profound,and makes the TRIZ problem-solving approach comprehensible to anyone with a knowledgeof basic algebra.Although TRIZ continues to evolve, its foundation remains intact—and is essential study for those pursuing a thorough understanding of this powerful methodology.Victoria RozaIdeation International Inc.

Also in this Section... Math Department The Walsh Jesuit High School mathematics program is designed to provide each student with a concrete background for any progression of math courses that he/she may choose to embark upon in his/her college career. In order to achieve this objective, the mathematics department has developed a series of courses that, along with fulfilling each student's post-secondary needs, should also challenge each student's present abilities. Because of the wide application of math to other areas of study, particularly the sciences, it is our goal to develop lifelong problem-solving skills. These skills should enable a student to be able to competently step into a world of ideas where the only tools are his/her mind and the ability to apply deductive mathematical reasoning to the solution of problems, mathematical and otherwise.

She is the author of Algebra Workbook For Dummies, Algebra II For Dummies, and Algebra II Workbook For Dummies. Most Helpful Customer Reviews It took me six weeks in the evening to read every word, practice and take notes for the future from this book (an after work project and I never missed a day). This is not one of those do it in a weekend Dummies books unless your very up on math. My math at school stopped at GCSE level but I did well in it. However I did do A level physics and picked up some in my first degree. The last time I did math was 1998-2001 I am 31 now (yeah what a laugh worked for years and never needed it). I am getting ready to do another degree in science (we live longer now so I thought why not). I have found this book a good get ready/revision book. I would not advise it for kids it goes very quick and often into more depth than school will on a topic. Good for a parent though who wants to help pull their kid along and needs a refresher and find the curriculum the kids use just too slow and verbose. I am just going on to Algebra 2 so I will drop a review when I finish it. Algebra is the key to computer programming, physics, calculus etc the list is endless and it starts here. This book is time well spent as it will shortcut learning fields in which algebra is used or borrowed from. This book is a good investment in that regard. Caveat this book will be really tough if you left school without any math qualifications you will need more rudimentary work first this does not cover general math at all...apart from a quick fire run at fractions, powers, roots, signs etc it just goes direct into algebra. Well it is an algebra book. :) It really is a superb book for learning algebra. However I quickly realised that I didn't quite reach up to the "Dummie" level. Whilst it explains the basics, if you wish to learn algebra there are other important mathematical milestones need to be reached first. I have had to put this book away and start learning skills and levels I am too embarrassed to list here! great book, great service!! Part of my uni computer course took in maths, serious maths, and this not being my best subject am prone to a struggle or two and actually think that I am number dyslectic consequently algebra frazzled my brain. This book starts with the basics - fractions - which are easy enough. Then we slowly progress through Factoring, Equations, Formulas, Graphs, and so it goes on. But the book is done so that an element of fun comes into the learning therefore making it easier to understand and retain in the old memory banks. Mary Jane Sterling has done a sterling job of making this book easy to read and algebra to understand. I have O level C grade and work in year 6 of a primary school as a TA. A basic knowledge of algebra seems to be necessary now to work in year 6 although I don't think it always was so I bought this book as I do not want to look stupid! I would say it assumes a knowledge of maths equating to about level 5 National Curriculum. I am finding it very helpful. I need to keep reading it as I need to know what 'simplify' means and also 'factorise'. I have forgotton now that I am getting on! As far as service is concerned there is little to say. Everything functioned reasonably well and the book arrived in good condition in a reasonable time. Regarding the book it seems to me a little more difficult to comment ... much depends on what people want. I bought the book to help my son review his Alegbra. The fact that he is not terribly motivated to read the book is certainly not the fault of the author. One impression we have had is that the book may not be the best approach for many teenagers: It seems to be structured more for °adults° that need a review of the basic concepts for one reason or another. Certainly the book doesn't cost that much so it's worth trying it out. For those motivated to review quickly it is certainly worth .it I love these books, i have purchased several for 2 of my daughters, they are so easy to understand and put everything in simple form that makes you think why do they just not teach the subject this way becaause it really does work, excellent product everytime. I hadn't placed my nose in a maths book since 1976 and wanted to gain a basis to understanding the subject in greater detail. The author presents the subject in a structured fashion and injects this book with plenty of humour to help get the concept across with as little pain as possible. There are plenty of books which make algebra seem dull and dreary, but this is definitely not one of them! I did not read this book from cover to cover, but used it build up an idea of the subject over time. Not having a teacher to help me, I had to rely purely on the text and because of the way this is written did not find it too difficult. I liked the book so much I bought her book, Algebra ll as well.

Knot Book: An Elementary Introduction to the Mathematical Theory of Knots… See more details below Knot Book: An Elementary Introduction to the Mathematical Theory of Knots available in Paperback, Hardcover Hardcover Item is available through our marketplace sellers. Overview understood with only a background of high school algebra and can be solved by the curious amateur. All you need to begin is a piece of string, a little math, a little imagination, and Colin Adams's The Knot Book - the first book to make cutting-edge research in knot theory accessible to a nonspecialist audience. What are the different properties and classifications of knots? How do you determine whether a knot is actually knotted or can be untangled? What is the appropriate measure of the complexity of a knot? What does knot theory research offer to other sciences? In The Knot Book Colin Adams describes and illustrates the work being done to answer these questions. Starting with the simplest knot (the trivial knot or unknot), Adams guides readers through increasingly more intricate twists and turns of knot theory, exploring problems and theorems mathematicians now can solve, as well as those that remain open. He also looks at how knot theory is providing important insights in biology, chemistry, physics, and other fields. Included are hundreds of illustrations of knots (including a table at the end of the book displaying nearly 200 different knots) as well as worked examples, exercises open problems - even a few knot jokes and pastimes. Colin Adams explains knot theory with an enthusiasm and an informal style that makes this seemingly mysterious subject easy to approach. With The Knot Book and a mathematical background that includes no more than a familiarity with polynomials, you will be able to understand and work with some of the discipline's most modern and provocative ideas. Editorial Reviews Booknews For the nonspecialist seeking the advanced merit badge, addresses such questions as the properties and types of knots, distinguishing between a true knot and a mere tangle, and measuring a knot's complexity. The emerging branch of mathematics dealing with knots is finding applications in DNA research and synthesizing new molecules, and is providing some interesting puzzles for statistical mechanics and quantum field theory. Does not cover knotholes. Illustrates nearly 200 knots. Annotation c. Book News, Inc., Portland, OR (booknews.com) From the Publisher "Adams is an expert in knot theory, and this shows in the clarity and accuracy of his writing, and in the rich store of examples and problems . . . We are going to see much more of knot theory and its applications, and this book is an excellent place to start." —Nature

0321069Built on AMATYC and NCTM standards, this book takes an active learning approach, focusing on collaborative for small groups. Independent learning is encouraged as problem-solving skills illustrate connections among mathematic ideas as readers discover and build on concepts explored as a group, as the book focuses on learning in a social context. Each section of a chapter opens with the investigation of a problem, in which readers gather data and collaborate on investigative activities. The book's discussion summarizes matheatic ideas gained from the investigations. At the end of each section concept maps enable readers to devise key ideas and draw connections between aspects of the concepts.

This includes being able to formulate and effectively communicate a problem analysis and solution using methods of calculus to recognize problem situations for which calculus methods are applicable, and to be able to understand analyses of such problem situations that make use of calculus methods to understand the general characteristics of the mathematical method. Admittedly, parts of this list are vague. Paradoxically, in order to understand a more specific set of objectives, you would already need to know calculus. The objectives would naturally mention new concepts and use terminology that you will learn in the course, but which would not make any sense to you now (unless you have already studied calculus). To make an analogy, imagine that you have completed a study of the arithmetic of whole numbers -- that is, addition, subtraction, multiplication, and division of integers greater than or equal to zero. Next you will take a course on the arithmetic of rational numbers. The goals of instruction would mention concepts like fractions, negative numbers, reciprocals. But until you have studied rational numbers, these terms have no meaning, or what is more confusing, a meaning in everyday usage that is quite different from the intended meaning in the course. In a sense, a math course is similar to a course in a foreign language. A fundamental goal is to master enough of the vocabulary and grammar and idiom to carry on a conversation. You might say that every mathematical subject corresponds to a different language, say Algebraish for algebra, Trigish in trigonometry, and Calculish for calculus. Of course, these aren't really separate languages. Each mathematical language is actually a specialized part of your normal language. That can give you a misleading impression. You can listen to me conversing in Calculish and think you are understanding it, because you understand the regular English parts of it. However, true understanding only occurs when we can communicate our ideas to each other, and that is impossible if my ideas concern concepts you have not yet learned. From this perspective, the point of studying calculus is to learn a new dialect of English, namely Calculish, and to learn it well enough to understand spoken and written conversation. In a word, your goal is fluency. Many students are required to take calculus as they pursue majors in other disciplines, like biology, or physics, or economics. If you are one of these students, fluency in Calculish is probably the most important goal of the course. That is because there are important applications of calculus in your major. Your completion of calculus 1 is not necessarily so that you can actively apply it in your future work, or even so you can make direct use of results others have obtained using calculus. Rather, it is so you can participate meaningfully in the conversation. This is a key observation about the objectives of the course. Learning the methods and memorizing the definitions and being able to solve homework problems accomplishes little or nothing if you do not gain fluency in the process. That is why the first objective listed above concerns conceptual understanding, and why writing coherently and correctly are also included. The last objective on the list is probably the vaguest of them all. It reflects the fact that mathematical knowledge is developed in a highly stylized form. Think of it as a combination of grammatical structure and idiomatic usage that underlies all mathematical language. True fluency demands an understanding of the grammar and idiom of the language. And this is especially true for mathematics, because its structure is so different from normal conversational language. Over the course of the semester, you will see how this structure appears in the specific context of calculus. The better you understand the structure, the greater your ability to converse fluently in Calculish. I refer to these as general characteristics of the mathematical method because they pervade all of mathematics. Developing an understanding of this structure of mathematical knowledge is an important general education goal, because it gives you access to a broad literature of mathematical analyses and methods.

We will determine when these lists of numbers, or sequences, have a pattern, when we can generalize that pattern to find any term and what it looks like if we sum up the numbers in the sequence. Let's start off with a few definitions and some terminology and from there we will see how we can determine their behaviorThis lesson was the second place winner in the 2012 SoftChalk Lesson Challenge.The lesson has the following objectives:... see more This lesson was the second place winner in the 2012 SoftChalk Lesson Challenge.The lesson has the following objectives: AState the integer that corresponds to a real-world situation.BGraph rational numbers on the number line.CConvert from fraction notation for a rational number to decimal notation.DDetermine which of two real numbers is greater and indicate which, using < or >.EFind the absolute value of a real number.FIdentify numbers that are members of the Real Number Numbers to your Bookmark Collection or Course ePortfolio Select this link to close drop down of your Bookmark Collection or Course ePortfolio for material The Real Numbers Select this link to open drop down to add material The Real NumbersWe have deveoped and provide access to an extensive, interactive self-review library covering 26 lecture modules in general... see more We have deveoped and provide access to an extensive, interactive self-review library covering 26 lecture modules in general astronomy to give students instruction tailored to their rate of learning and mathematical abilities, with personal feedback, as they integrate new knowledge into their existing view of the universe. Students typically complete 1,600 problems over a semester, drawing from an archive of over 12,000 questions presenting both conceptual and mathematically-focused challenges.A companion instructor analysis tool for reviewing student work archives copies of each exercise completed by every student, including the details of incorrect answers, and reveals trends with topic and time for individuals and groups.
