Solving The Math Homework Hurdle
Math is a common obstacle for all students. The typical mistake being done is letting their fear of math affect their solving process. It even reaches a point in which students think they can't understand the simplest lesson in their class. These can translate into unproductive time. Students will just stare at their textbooks not knowing how to proceed. Fortunately, students can use this service if it becomes too hard.
Understanding a particular math problem can be hard even for the brightest of students. Such as the algebra. All level of students from high school through college find it necessary to review the basic concepts of algebra when a test is coming up. When it comes to standardized tests, algebra is an integral part.
Having unknown factors in algebra can be intimidating for some students that are used to solving more straightforward equations. The concepts are usually complex, and the symbols being used can appear like a foreign language for some. The problems might seem intimidating and unfamiliar. However, once the student gets a grasp of the basic logic behind algebra, solving the presented equations can be manageable. Now the important part is to build your understanding from the bottom to the top. This will ensure your success with algebra. You will stop seeing algebra not just being a system of arbitrary rules, but instead, an equation that makes sense to them. You do not need to be frustrated and lost, any student with the right tools can learn to approach algebra equations and solve it correctly.
Now if a student is having a hard time with math, it is essential to assess the reasons on why. Is there a learning style in which they can work better? Are there obstacles that impede their learning? Lack of attention perhaps? Or just a poor grasp of the basic concepts of equations? Understanding which one affects a student can greatly help the teacher provide a better learning environment for his or her pupils.

This quantity is the court cases of the tenth foreign Symposium on utilized Algebra, Algebraic Algorithms and Error-Correcting Codes (AAECC 10),held in Puerto Rico, may perhaps 1993. the purpose of the AAECC conferences is to draw high-level examine papers and to inspire cross-fertilization between diverse components which proportion using algebraic tools and strategies for functions within the sciences of computing, communications, and engineering. The AAECC symposia are more often than not dedicated to study in coding concept and computing device algebra. The theoryof error-correcting codes bargains with the transmission of data within the presence of noise. Coding is the systematic use of redundancy in theformation of the messages to be despatched for you to allow the restoration of the data current initially after it's been corrupted through (not too much)noise. computing device algebra is dedicated to the research of algorithms, computational tools, software program structures and machine languages, orientated to medical computations played on detailed and sometimes symbolic information, via manipulating formal expressions by way of the algebraic principles they fulfill. Questions of complexity and cryptography are evidently associated with either coding idea and computing device algebra and signify an enormous proportion of the world coated by means of AAECC.

How I organised my notes for college #2
This second part is going to be about how I organised my Maths notes.
For my Maths notes, I used the hardcover notebooks (the ones I showed in part 1) for each of my modules. I did Further Maths A level so I did quite a number of modules. I also used A4 refill pads very often to do assignments and practice questions.
The notes in the photo above were for the Core 4 module. I only used different colours for the titles and formulas coz the notes mostly consisted of calculations.
This module (Statistics 2) however, was a nicer one coz it had lots of diagrams so I was able to use lots of colour to make the notes look less boring.
These resource packs were sold in our college shop for just £1. They were very useful for revision.
Inside the pack were notes for each topic in that module along with examples and illustrative diagrams. I sometimes made summary notes on A4 paper from these notes.
When revising, I always made sure I understood the concepts first by going through notes and some examples then I moved on to practice questions and past paper questions. I did almost every past paper I could find ranging from the resource pack to the MEI website.
This booklet given to us by the college was also very useful as it had formulas and tables for all the modules. We were given the same booklet during the exam but it helped to have it with you during revision as well.
Another thing we were given by the college was this condensed formula booklet which was made by Loughborough university.
It had all sorts of Maths formulas you could ever think of ranging from Algebra to circles to sine, cosine and tangent graphs and some other stuff I didn't really know.
I thought it was a useful because I could take it anywhere and not have to carry around the bigger formula booklet.
Maths for me, was all about practice. Once you are able to grasp the concept or understand how to do it, the only thing left is to do as many practice questions as possible. Practice makes perfect | 677.169 | 1 |

Basics of Discrete Mathematics
The subject makes students acquainted with some basic methods of discrete mathematics employed in (not only technical) practice. The content can be divided into four areas. The first of them is logic, especially the propositional and predicate logic, and its applications in computer science. The second area is formed by the graph theory with an emphasis on the graph algorithms utilized for solving optimization problems of different kinds. The next area is algebra and its applications in the theory of formal languages and automata. The last area is represented by the fundamentals of coding theory, especially the linear codes are discussed.
Students will learn basic facts about logic, graph theory, automata theory, formal languages and coding theory. This will be useful for research in their specializations and for affective use of computers because they will better understand the principles computers work on.
The course is taught through lectures explaining the basic principles and theory of the discipline.
Assesment methods and criteria linked to learning outcomes
Students are to pass an exam. During the exam their knowledge of the concepts introduced and of the basic propertief of these comcepts will be assessed. Also their ability to use theoretic results for solving concrete problems will be evaluated.

Mathematics Curriculum in the US - Research Paper Example
Extract of sample Mathematics Curriculum in the US
As people compete in the modern century, they stand on the main changes threshold in the United States curriculum of mathematics education. This paper seeks to identify some of the main changes in the mathematic curriculum in the US and highlight how teachers will make some adjustments in their teaching styles to accommodate these drastic changes. Discussion An increasing anxiety in the US concerning the mathematics education state is evident. The challenge is evident in the poor USlearners' performance on different global evaluations. People have assumed that they only require one established mathematical skill body in preparation of the twenty first century careers. This assumption has led to increased anxiety. The reality is; diverse mathematics skills sets are crucial foundation for various careers. Therefore, the current mathematics skills must be altered and reshaped to reflect such fact. The fundamental premises of this discussion is that mathematic curriculum in the United States is and has been undergoing drastic changes in the recent past and teachers must restructure the curriculum of mathematics in the United States - in terms of methods of teaching and the content of their teaching materials- to be competent and competitive in the modern world. Therefore, if students are to develop current mathematic knowledge and confidence in order to utilize that knowledge – and be individually and professionally competitive and competent in the 21st century - teachers and instructors have a crucial role to play in reshaping their tactic and techniques to fit and adjust to the constantly changing mathematic curriculum of the US. This restructuring entails a lot more than just inventing new teaching materials or retaining educators, (Russell, Corwin, Mokros, Friel & Stone, 1992). Similarly, changing some parts is insufficient, what is needed is a total reshaping or redesigning of the school content of mathematics curriculum, as well as the teaching methods. Some of the main changes in the US mathematic curriculum The crucial changes include first alterations in the mathematical operations requirements. As the US economy adapts to the current information era requirements, workforce in all sectors such as hotel secretaries and clerks, travel agents, mechanics of automobiles and many others should learn to explain and interpret competently modern IT controlled procedures. Various jobs presently need analytical and not peculiar mechanical knowledge and skills, therefore, all learners require increasingly mathematical intelligent in colleges as a preparation for such opportunities. In addition, the intensive utilization of financial, graphical, and statistical information in everyday magazines, and public media and debates demands increased quantitative literacy standards for efficient engagement in democratic community, (Russell, 1997). In the United States, there exists a shift towards the standards of common core, demanding an combined and an increasingly comprehensive mathematics curriculum. Even though, United States has witnessed a complete sample paper, it is clear that increasingly multi-dimensional queries will be extremely based on problem-solving standards, requiring the learners to utilize various skills to attain various solutions. Such a new move is increasingly encouraged, but from the perspective of teachers, such a change must be carefully introduced. To attain successful outcomes, the new questioning style must aid students realize where maths is applied in daily life. This is crucial chance to change the pseudocontext tradition of textbooks, whereby fake actual world samples contain a mathematical query. Common core evaluations and other functional knowledge present a crucial opportunity to indicate the mathematics

This book, first published in 2003, uses categorical algebra to build such a foundation, starting from intuitive descriptions of mathematically and physically common phenomena and advancing to a precise specification of the nature of Categories of Sets. Set theory as the algebra of mappings is introduced and developed as a unifying basis for advanced mathematical subjects such as algebra, geometry, analysis, and combinatorics. The formal study evolves from general axioms which express universal properties of sums, products, mapping sets, and natural number recursion. The distinctive features of Cantorian abstract sets, as contrasted with the variable and cohesive sets of geometry and analysis, are made explicit and taken as special axioms. Functor categories are introduced in order to model the variable sets used in geometry, and to illustrate the failure of the axiom of choice. An appendix provides an explicit introduction to necessary concepts from logic, and an extensive glossary provides a window to the mathematical landscape. less

A Day of Mathematics
a symposium sponsored by EDC's Center for Mathematics Education and the Massachusetts Department of Elementary & Secondary Education
Location:
Tyngsboro, Massachusetts
The symposium provided teachers of Algebra 2 and other grade 11–12 high school courses with a chance to
explore several important mathematical areas relevant to the high school curriculum,
work with the latest technology that will soon make its way into high school classrooms,
talk with representatives from higher education and business about the algebra needed by high school graduates in order to succeed in postsecondary institutions, and
meet and talk with colleagues from around the state.
In addition to panel discussions and a keynote address by Bill McCallum, the symposium involved two breakout sessions in which teachers had a choice of one of four concurrent workshops, each demonstrating a different use of function modeling language (FML) in the high school mathematics curriculum:
"Computer algebra systems and high school mathematics," Ryota Matsuura and Sarah Sword.
"How does the bank figure the monthly payment on a loan?" Jean Benson and Doreen Kilday. | 677.169 | 1 |

Book Description
These are the entire 23 lessons of Graph Theory taught in Department of MathematicsUniversity of Tennessee at Chattanooga. It utilizes a java software, Petersen, written by Christopher P. Mawata which can draw, edit and manipulate simple graphs, examine properties of the graphs, and demonstrate them using computer animation. The software can display information about a graph like the number of vertices and their degrees, the adjacency matrix, the number of components, and articulation points. It can find complements of graphs, line graphs, find the chromatic number of a graph, check if a graph is bipartite, check if two graphs are isomorphic or if one graph is a subgraph of another and find the dual graph of a planar graph in many cases. Petersen also demonstrates Euler and Hamilton circuits, searches, and algorithms for finding minimum spanning trees.
These lessons are targeted at undergraduate beginning classes in Graph Theory. The students who use the software at UTC, the University of Tennessee at Chattanooga, are mathematics majors for whom it is an elective course and computer science students for whom it is a required course. It is assumed that the students using the software and lessons have some measure of mathematical sophistication; for instance that they are able to write an induction proof etc. They have done second semester calculus and a course in computer programming. The prerequisite courses give an indication of the level of mathematical maturity assumed. The Petersen software will run under Windows 3.1, Windows 95 or better. | 677.169 | 1 |

Mathematics Major - First Three Years
Grand Valley State College opened its doors to students in September 1963. During the 1963-64 academic year, only one mathematics course was taught, which was Mathematics 1 – Introduction to College Mathematics. In fact, during that first academic year, only courses that were part of so-called Foundation Program were taught. The Foundation Program was a set of nine courses that all students were required to take. The Foundation was considered by its designers as a centerpiece for a public, liberal arts college. (The 1963-64 catalog indicated that a Calculus and Analytic Geometry course would be offered in 1963-64 for those students who were granted an exemption from the mathematics foundation course, but it appears that it was never offered.) After completing their first year in the Foundations Program, students would then begin their major field of study.
The plan was that the various majors would be developed by the faculty members during the first year and courses in the major would be offered beginning in the second year. Dr. Marvin De Vries taught Mathematics 1 in 1963-64. He was one of the original 15 faculty members at Grand Valley and started his career at Grand Valley as an Assistant Professor of Mathematics and Economics. He was, however, an economist and so the original faculty did not have a mathematician. So while the curriculum was being developed for many majors, there was little work at developing the mathematics curriculum during the first year. Consequently, there were no descriptions of mathematics courses in the 1964-65 catalog except for the mathematics course in the Foundation Program. However, the following was given as the requirements for a major in mathematics.
The major program in Mathematics will involve completion of a selection of the following courses:
These requirements for a mathematics major appear to have never been implemented since the requirements for a mathematics major were changed during the 1964 – 65 academic year. Grand Valley hired two mathematics faculty members for the 1964-65 academic year: Dr. Dan Clock and Prof. Don Vander Jagt. (Prof. Vander Jagt completed his Ph.D. while at Grand Valley in 1973 from Western Michigan University.) The mathematics major, the calculus sequence, and service courses in mathematics were developed during the second year by Profs. Clock and Vander Jagt. They set the following requirements for a mathematics major and these first appeared in the 1965 – 66 catalog.
Mathematics Major (1965 – 66 Catalog)
A student majoring in mathematics is required to take at least 45 hours in mathematics, exclusive of courses 101 (Introduction to College Mathematics) and 121 (Algebra and Trigonometry). The major program is to be planned with the approval of a faculty adviser. The student must complete
Each student must also participate in the mathematics colloquium during his senior year and must complete Physics 230 – Principles of Physics and History of Science 480 – History of Mathematics and at least three additional courses from the following group:
Although the terms were not used at that time, this set the basic format for the mathematics major as consisting of a set of core courses required by all majors, a set of elective courses in the major, and a set of cognate courses, which are courses outside of mathematics but in areas related to mathematics or in which mathematics is used.
Elementary and Secondary Certification
At this time, there were no emphases within the major. All mathematics majors were to complete these requirements, including those seeking elementary or secondary teaching certification.
For elementary certification, a student was required to:
Complete the requirements for graduation including a major;
Complete the following courses (35 credits in the quarter system):
PSY 201 – Introduction to Psychology
PSY 301 – Human Growth and Development
ED 303 – Teacher Aid Program
ED 304 – Methods Seminar
ED 403 – Practice Teaching, and
ED 408 – Contemporary Issues in Education
A planned Distribution Program including an art course, at least one sophomore or junior course in English, HST 201 – The Historian and American History, two courses in a modern language in addition to the two courses in the Foundation Program, MUS 301 – Historical Survey of Music, MTH 221 – The Real Number System, and one additional Natural Science elective. | 677.169 | 1 |

About this Course
Math is everywhere. In this class, you'll gain an in-depth understanding of algebraic principles, many of which you may have seen before, and learn how to use them to solve problems that we encounter in everyday life. The online version of College Algebra will cover all of the topics that you would see in more traditional class formats, but it will present the material in a way that we hope you'll find fresh and interesting. You will learn about functions, polynomials, graphing, complex numbers, exponential and logarithmic equations, and much more, all through exploring real-world scenarios | 677.169 | 1 |
Math and Science
Our math and science courses are typically yearlong and involve laboratory and experiential work. In all classes, we strive to make our students informed citizens of the modern world. We believe that students must understand where knowledge comes from, how it can be effectively used in society, and how scientific and mathematical thought will be incorporated into their lives and careers.
Current Courses – Math
Algebra I This course is the foundation for high school mathematics courses. Topics include the real number system, simplifying expressions, solving multi-step equations, evaluating and solving linear, quadratic, radical, and rational equations, solving one-variable, compound, linear, and absolute-value inequalities, and solving systems of equations. Real world applications are presented within the course content, and a function's approach is emphasized. The successful Algebra I student will be prepared for Geometry.
Algebra II Algebra II is the last truly sequential course in the high school curriculum, in that while it prepares students to go on to Pre-Calculus, it also gives the student the background to take Statistics in addition at a later time in their math careers (which is highly encouraged, as just about everyone would benefit from a basic understanding of Statistics). Topics of the course shall include but are not limited to in-depth analysis of functions (linear, quadratic, rational and so on) and of systems of functions. Exponential and logarithmic functions as well as sequences and series are included, as well as an introduction to basic statistical ideas (normal probability, measures of center and spread, and basic inferential concepts and the like).
Geometry We will bridge the gap between the abstraction of Algebra I and the physical world of Geometry by looking at how we can graph the language of math to show how the numbers work and can be physically represented. The large topics covered this year will be the following: the building blocks of Geometry (point, line and plane), constructing geometric shapes and figures, line and angle properties, triangle, polygon and circle properties, the Pythagorean Theorem, and basic trigonometry.
Statistics Knowledge of statistics is important for people in all walks of life and within a wide range of academic fields of study such as biological and environmental sciences, physical and behavioral sciences, medicine, business and economics. The course will include but not be limited to the study of data analysis, probability, pattern analysis, experimental design, simulation and statistical inference. An emphasis on the gathering of data, both categorical and quantitative, from the real world around us will be core in this course, as well as rigorous ways to analyze and explain it in a variety of ways.
Pre-Calculus This course will build on the foundation of your Algebra II math course and will prepare you for Calculus. Topics include characteristics (domain, range, roots, end-behavior, limits, intervals of increasing and decreasing, and graphs) of linear, quadratic, cubic, higher-degree polynomial, exponential, logarithmic, absolute-value, rational, radical, piecewise and trigonometric functions. The rule of four, which refers to representing mathematical functions with graphs, tables, equations, and words, will be used. In addition, you will learn about geometric and arithmetic sequences and series, and you will be introduced to topics of Calculus.
Introduction to Calculus The overall goal of this course is to help students understand and apply two of the three big ideas of AB Calculus: limits and derivatives. Imbedded throughout the big ideas are the mathematical practices for Calculus: reasoning with definitions and theorems, connecting concepts, implementing algebraic/computational processes, connecting multiple representations, building notational fluency, and communicating mathematics orally and in well-written sentences.
AB Calculus This is a college-level calculus course designed to meet the Advanced Placement curricular requirements for Calculus AB (equivalent to a one-semester college course). The major topics of this course are limits, derivatives, integrals, and the Fundamental Theorem of Calculus. We will investigate and analyze course topics using equations, graphs, tables, and words, with a particular emphasis on a conceptual understanding of calculus. Applications, in particular to solid geometry and physics, will be studied where appropriate.
AP Calculus BC The development and subsequent use of calculus to understand and to represent many aspects of the world around us has opened opportunities and encouraged advancements beyond the comprehension of those who first defined its use. My primary objectives in the classroom are to inspire in students an appreciation of the power and beauty of calculus; to enable them to understand and to apply the big ideas of limits, derivatives, integrals, and series; and to give them a strong foundation for future study. This foundation will emphasize the development of skills and the communication of concepts. It will cover—at a minimum—the structural components of the curriculum framework from Calculus BC as defined by the College Board.
Current Courses – Science
Astrobiology Astrobiology is an integrated lab science course that addresses the questions "Is there life elsewhere in the universe? What is life's future on Earth and beyond? How did life originate on Earth?" We will study fundamental concepts from many of the science disciplines – biology, chemistry, physics, astronomy, and Earth science – in order to explore these very complex topics. In recent years, astrobiology has become the focus of a significant amount of academic research, and we will be investigating both the latest findings and the nature of the scientific methods researchers employ in this field.
Biology This class is designed to explore the workings of living organisms on multiple levels, including molecular, cellular, organismal, and ecological, and to explore overarching themes that connect each level to the next. Four interdisciplinary units – the bubonic plague, cancer, viruses in the body, and the Serengeti Plains – serve as frameworks to explore topics such as cell structure and function, genetics, molecular biology, energy transformations, evolution and classification, biochemistry, and biodiversity. Current scientific research is introduced throughout the course, and students will explore the development of scientific thought and its applicability to situations and problems faced by society today.
Introduction to Engineering Introduction to Engineering has two goals: 1) to give students a chance to explore the engineering design cycle and its similarities to the process of scientific discovery; and 2) to expose students to the wide range of engineering disciplines. Students will learn the iterative process of defining and delimiting a problem, designing a solution, and then optimizing that solution – the essence of problem-solving in any subject. Multiple projects throughout the year will provide students with chances to experience this process in areas such as mechanical engineering, chemical engineering, biomedical engineering, and civil engineering.
Physics Physics is the study of our reality by applying an understanding of the properties of motion, matter, energy and force. Many concepts in Physics are expressed in mathematical terms and are subject to mathematical reasoning. Why this is, and what the advantages thereof are, is a major focus of the course. Wherever possible, this course will be taught in a "data first" way, meaning that while labs will be about collecting data in as useful ways as possible, class will often be about using lab results to build a new idea, not to confirm one already given by a book or some other source. After some initial handholding, students will be encouraged to participate in the creation of their own lab experiments. Though the teacher will generally contribute to the path of exploration that the labs represent somewhat more than the students do, it will often be by asking questions rather than stating facts. Even during class, the course will focus on analytical and critical thinking skills within the realm of physics over and above the learning of a set of convenient facts.
Science and Society This course will examine the interplay between the scientific world and society at large. We will start by exploring how the modern scientific enterprise works through the lens of research on addiction and mental illness. Afterwards, we will investigate how science interacts with the law, how it informs government policy, how science intersects with the media, and conversely how all three areas affect the practice of and societal perceptions of science. | 677.169 | 1 |

DESCRIPTION OF COURSE CONTENT:
``All fields of science and engineering rely heavily on numerical
computing. The traditional two branches of science are theoretical
science and experimental science. Computational science is now often
mentioned as a third branch, having a status that is essentially equal to,
perhaps even eclipsing, that of its two older siblings. The availability of
greatly improved computational techniques and immensely faster computers
allows the routine solution of complicated problems that would have
seemed impossible just a generation ago.''
-- Michael L. Overton, Courant Institute of Mathematical Sciences
This course provides a deeper look into the computational aspects of many numerical techniques used for solving otherwise intractable problems in science and engineering. It also serves as an introduction to scientific programming in the numerical MATrix LABoratory language MATLAB. MATLAB is a high-performance language for technical computing. It integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation.
STUDENT LEARNING OUTCOMES:
Students will be able to use the numerical MATrix LABoratory language (MATLAB) for scientific programming applications. Students will be able to demonstrate knowledge of how numbers are represented in a computer system and discuss presence of computer errors in representing numbers. Students will become familiar with a variety of numerical methods for solving mathematical problems that involve systems of linear equations; nonlinear equations/systems; definite integrals; first- and higher-order derivatives; and polynomial interpolation. Students will be able to apply numerical methods to solve real-world problems that involve models of the five mathematical types listed above; to discuss the advantages and disadvantages of the implemented methods; and to write and present a short report (term paper) in front of an audience of peers/classmates.
"As the instructor for this course, I reserve the right to adjust this schedule in any way that serves the educational needs of the students enrolled in this course. -Hristo V. Kojouharov."
GRADING POLICY:
Grades are based on weekly homework assignments, two midterm
exams, and a term paper. There is no extra credit.
Homework Assignments (10%): Theoretical and computational problems will be assigned regularly throughout the semester. Homework will usually be assigned weekly on Thursdays, and written reports will be due the following Thursday. Teamwork is encouraged.
Two Mid-Term Exams (70%): Each mid-term exam will be given during a class period and you will have 80 minutes to take it. Exams will be made up of questions similar to the assigned homework problems. A tentative schedule of the exams is as follows: Exam #1 - Thursday, March 22, 2018; Exam #2 - Thursday, April 26, 2018. Topics and exact dates for each exam will be announced in class at least a week in advance.
Make-ups for exams will be given only for the
university approved absences,
and should be discussed prior to the exam.
Term Paper (20%): A short report discussing the numerical solutions, interpretation, and comparison of the results of a project must be submitted at least one week before the last day of classes. The project should be about a real-world problem and you should implement two different numerical algorithms, in a computer language of choice or use any available software, to solve it. I highly encourage the use of MATLAB for this project. A hard-copy of the term papers must be submitted by Thursday, May 3, 2018. In addition to a hardcopy submission, the term papers should be orally presented in class during the last week of classes.
Grading Scale:A = 90+; B = 80-89; C = 70-79; D = 60-69; F = 59-
Students are expected to keep track of their performance throughout the semester and seek guidance from available sources (including the instructor) if their performance drops below satisfactory levels.

Math 320: Linear Algebra and Differential Equations
Student Body:
Students in the Sciences and Engineering
Background and Goals:
Differential equations are the fundamental tools that modern science and engineering use to model physical reality. The importance of differential equations to these disciplines cannot be overemphasized. A distinct subject in its own right, linear algebra is a part of mathematics concerned with the structure inherent in mathematical systems. We shall study these subjects together for three reasons: (1) The viewpoint of linear algebra is immensely helpful in uncovering the order underlying the topic of differential equations; it helps us understand the ``why'' and not just the ``how'' of our calculations. (2) Linear algebra is essential to the theory of differential equations. And (3) linear algebra is crucial to the computer approximations which are often the only way to solve the most challenging differential equations.
Alternatives:
For a more thorough study of linear algebra and differential equations the student should choose Math 340 and Math 319 | 677.169 | 1 |

DEFINITION A matrix is a tool that monitors numbers geared up into rows and columns. The size of the matrix is the variety of rows by means of the variety of columns. A process of linear equations might be lowered to a matrix of numbers by means of permitting every one row to symbolize one equation, and every column a variable or the constants. The matrix comprises simply the coefficients and constants. Matrices provides how to practice repetitive mathematics initiatives through one matrix operation. earlier than you start plugging info right into a matrix, although, you must be aware of the foundations of matrix mathematics.
There'll be x-intercepts if the discriminant of the corresponding equation is optimistic. but when the discriminant is zero, merely the vertex, or turning element, of the parabola will contact the x-axis. A parabola that floats solely above or completely lower than the x-axis corresponds to an equation with nonreal suggestions. Key issues for the father or mother parabola can be the vertex (0, zero) and (1, 1) and (–1, 1), otherwise you may also use (2, four) and (–2, four) to aid set the curvature of the parabola. differences observe to the parabola as to the other graph family members, yet figuring out the vertex and the intercepts will be adequate. | 677.169 | 1 |

The focus is on L-functions. These are at the center of much research today. Themes: Euler products; analytic continuation and functional equations; special values; relations among different kinds of L-functions. Briefly there are two broad classes of L-functions: those that arise from automorphic forms and those that arise from geometry.
There are conjectural relations between the L-functions of the first kind with those of the second kind. We start with the classical Dirichlet L-functions and move on to the L-functions defined by modular forms. We give an exposition of Tate's thesis which gives a unified account of the L-functions that arise from abelian characters of Galois groups. We also give an introduction to L-functions arising from algebraic varieties, for instance algebraic curves. We then describe relations, proven and conjectural among these. This course is more like a seminar. The topics and level will depend on the students. Each student will have a project to do, with a written report and a lecture exposition.

Text: Matroid Applications edited by Neil White (Chapter 6: The Tutte Polynomial and its Applications by Thomas Brylawski and James Oxley)
The theory of numerical invariants for matroids is one of many aspects of matroid theory having its origins within graph theory. Most of the fundamental ideas in matroid invariant theory were developed from graphs by Veblen, Birkhoff, Whitney, and Tutte when considering colorings and flows in graphs. This course will introduce the Tutte polynomial for matroids and will consider its applications in graph theory, coding theory, percolation theory, electrical network theory, and statistical mechanics. | 677.169 | 1 |

Discrete mathematics forms the mathematical foundation of computer and information science. It is also a fascinating subject in itself.
Learners will become familiar with a broad range of mathematical objects like sets, functions, relations, graphs, that are omnipresent in computer science. Perhaps more importantly, they will reach a certain level of mathematical maturity - being able to understand formal statements and their proofs; coming up with rigorous proofs themselves; and coming up with interesting results.
This course attempts to be rigorous without being overly formal. This means, for every concept we introduce we will show at least one interesting and non-trivial result and give a full proof. However, we will do so without too much formal notation, employing examples and figures whenever possible.
The main topics of this course are (1) sets, functions, relations, (2) enumerative combinatorics, (3) graph theory, (4) network flow and matchings. It does not cover modular arithmetic, algebra, and logic, since these topics have a slightly different flavor and because there are already several courses on Coursera specifically on these topics.
Week 1 - Introduction - Basic Objects in Discrete Mathematics This module gives the learner a first impression of what discrete mathematics is about, and in which ways its "flavor" differs from other fields of mathematics. It introduces basic objects like sets, relations, functions, which form the foundation of discrete ...
Week 2 - Partial Orders Even without knowing, the learner has seen some orderings in the past. Numbers are ordered by <=. Integers can be partially ordered by the "divisible by" relation. In genealogy, people are ordered by the "A is an ancestor of B" relation. This module formally i...
Week 3 - Enumerative Combinatorics A big part of discrete mathematics is about counting things. A classic example asks how many different words can be obtained by re-ordering the letters in the word Mississippi. Counting problems of this flavor abound in discrete mathematics discrete probabilit...
Week 4 - The Binomial Coefficient The binomial coefficient (n choose k) counts the number of ways to select k elements from a set of size n. It appears all the time in enumerative combinatorics. A good understanding of (n choose k) is also extremely helpful for analysis of algorithms.
Week 5 - Asymptotics and the O-Notation
Week 6 - Introduction to Graph Theory Graphs are arguably the most important object in discrete mathematics. A huge number of problems from computer science and combinatorics can be modelled in the language of graphs. This module introduces the basic notions of graph theory - graphs, cycles, paths...
Week 7 - Connectivity, Trees, Cycles We continue with graph theory basics. In this module, we introduce trees, an important class of graphs, and several equivalent characterizations of trees. Finally, we present an efficient algorithm for detecting whether two trees are isomorphic.
Week 8 - Eulerian and Hamiltonian Cycles Starting with the well-known "Bridges of Königsberg" riddle, we prove the well-known characterization of Eulerian graphs. We discuss Hamiltonian paths and give sufficient criteria for their existence with Dirac's and Ore's theorem.
Week 9 - Spanning Trees We discuss spanning trees of graphs. In particular we present Kruskal's algorithm for finding the minimum spanning tree of a graph with edge costs. We prove Cayley's formula, stating that the complete graph on n vertices has n^(n-2) spanning trees.
Week 10 - Maximum flow and minimum cut This module is about flow networks and has a distinctively algorithmic flavor. We prove the maximum flow minimum cut duality theorem.
Week 11 - Matchings in Bipartite Graphs We prove Hall's Theorem and Kőnig's Theorem, two important results on matchings in bipartite graphs. With the machinery from flow networks, both have quite direct proofs. Finally, partial orderings have their comeback with Dilworth's Theorem, which has a surpr...
Actually I haven't finished course in the eleventh week yet, I've only done all the tests:). However, I'd like to say that I like this course very much, it's inspiring and difficult enough. Though I always have to struggle a lot to find the cocepts and meaning of the notations online, there have been enough hints. The only pity was that sometimes there's something which can't be shown normally in exercise, this has caused me some trouble. Overall it's great, and thanks a lot, professor Scheder.
The level is advanced undergraduate. It contains challenging excersises. You spent more than 10hr per week to solve them and typesetting them(at least for me).And you can make friend with your peers. It is for me a unique experience!
Poor presentation of material. Peer reviewed material with no solutions given and no explanation or solutions to any problems. The instructor is teaching this as a review course instead of for people who are taking this for their first time. You cannot learn in this course. Very poor. Remove this course its a waste of time.
Other than the issue of peer grading, I took the course of the first week and found the course material is missing and quiz of week 1 needs the materials of week 2.This is not a preliminary discrete math course. I was trying to learn part of the MIT discrete math course then jump on this course to catch up but I found that the first week's content is about 15 week content in MIT so I guess I will just quit.In the forum there are people seems can't find enough companies for peer grading and almost no posts after week 2.
Course materials are poorly prepared and the method of peer review of proofs in fundamentally flawed. Hopefully, once there are some teaching and explanatory materials available and an improved scheme for assignment marking, the course will be worth taking. Unfortunately it is a bit of a mess at the moment.
After more than 20 courses taken in Coursera (mostly in Math, Ecomonics and Computer Science), this is, by far, the WORST course I have ever taken. The content is fine but it very badly designed as MOOC. I am droping this course after the first week.On the Peer Graded Assignments it became very clear that most students simply did not have enough math background for the course. I peer reviewed 4/5 assignments and on most of then I graded zero. The problem is that these same students will peer review your assignments. Therefore, you dedicate your time and you will be evaluated by people that do not even know what the correct answer is, what is the point on this? I felt as being part of bad experiment...Given this a MOOC with thousand of students enrolled, the organizers must implement a fair format to grade the students. It is very clear Peer Graded Assignments format that was implemented is not a option, it put your grade on other's hands.This will simply repel any student that want to take a serious course and would really undesrtand the course content.This was a recurrent complaint on the forum, but nothing real was done. I logged a message on the forum, but the TA and organizers never replied.
Curiously this problem is not happening on the course "Introduccion to Enumerative Combinatorics" that implemented a better format to grade the students.
I am not sure if Coursera could do anything about, I just hope Coursera take this feedback seriouly and try to implement higher standards to prevent courses like this. | 677.169 | 1 |

A First Course in Linear Algebra
A First Course in Linear Algebra is an introductory textbook designed for university sophomores and juniors. Typically such a student will have taken calculus, but this is not a prerequisite.
Description
The book begins with systems of linear equations, then covers matrix algebra, before taking up finite-dimensional vector spaces in full generality. The final chapter covers matrix representations of linear transformations, through diagonalization, change of basis and Jordan canonical form. Along the way, determinants and eigenvalues get fair time.

Mathematics disorder Photo by: dan talson Definition Mathematics disorder, formerly called developmental arithmetic disorder, developmental acalculia, or dyscalculia, is a learning disorder in which a person's mathematical ability is substantially below the level normally expected based on his or her age, intelligence, life experiences, educational background, and physical impairments. This disability affects the ability to do calculations as well as the ability to understand word problems and mathematical concepts. Description Mathematics disorder was first described as a developmental disorder in 1937. Since then, it has come to encompass a number of distinct types of mathematical deficiencies. These include inability to perform calculations • inability to comprehend word problems The range and number of mathematical difficulties that have been documented suggests that there are several different causes for mathematics disorder. In addition, several known physical conditions cause mathematics disorder. Turner syndrome and fragile X syndrome, both genetic disorders that affect girls, are associated with difficulty in mathematics. Injury to certain parts of the brain can also cause inability to perform calculations. These conditions appear to be independent of other causes of mathematics disorder. Mathematics disorder is often associated with other learning disorders involving reading and language, although it may also exist independently in children whose reading and language skills are average or above average....

A Gentle Introduction to Category Theory: the calculational approach
A Gentle Introduction to Category Theory: the calculational approach by Maarten M. Fokkinga
Publisher: University of Twente1994 Number of pages: 80
Description: In these notes we present the important notions from category theory. The intention is to provide a fairly good skill in manipulating with those concepts formally. This text differs from most other introductions to category theory in the calculational style of the proofs, the restriction to applications within algorithmics, and the omission of many additional concepts and facts that I consider not helpful in a first introduction to category theory.

Advanced Placement Calculus (also known as AP Calculus, AP Calc AB / AP Calc BC, or AP Calc) is used to indicate one of two distinct Advanced Placement courses and examinations offered by College Board in calculus: AP Calculus AB and AP Calculus BC.
AP Calculus AB
AP Calculus AB is an Advanced Placement calculus course taken by high school students. The course is traditionally taken after precalculus and is the first calculus course offered at most schools except for the regular calculus class. The Pre-Advanced Placement pathway for math will help prepare students for further Advanced Placement classes and exams.
Purpose
The AP Program includes specifications for two calculus courses and the exam for each course. The two courses and the two corresponding exams are designated as Calculus AB and Calculus BC. Calculus AB can be offered as an AP course by any school that can organize a curriculum for students with advanced mathematical abilityDerivative in Real Life8:23

As Stanford University Education Professor William Damon says, schools need to give students a better understanding of why they are in school in the first place. In particular, students need to know why they are learning what is being taught. They need to understand how the knowledge and skills they are learning can help them accomplish their life goals. That is the only way to motivate students in a lasting way. (Tully, Susannah, "Helping Students Find a Sense of Purpose," The Chronicle Review, March 13, 2009, p. B14-B15.)
The "No Child Left Behind" Act has focused attention on reading and mathematics, assuming that students would understand that these subjects are important. But, as we have found in writing this booklet, neither students nor, surprisingly, their teachers are able to cite simple practical applications of elementary algebra. Hence it is no wonder that student motivation is so weak.
We believe that by presenting simple practical applications of algebra, students will gain a clearer understanding of why they are studying this subject.
As Professor Damon elaborates:
Students learn bits of knowledge that they may see little use for; and from time to time someone at a school assembly urges them to go and do great things in the world. When it comes to drawing connections between the two—that is, showing students how a math formula or a history lesson could be important for some purpose that a student may wish to pursue—schools too often leave their students flat.
If you visit a typical classroom and listen for the teacher's reasons for why the students should do their schoolwork, you will hear a host of narrow, instrumental goals, such as doing well in the course, getting good grades, and avoiding failure, or perhaps—if the students are lucky—the value of learning a specific skill for its own sake. But rarely (if ever) will you hear the teacher discuss with students broader purposes that any of these goals might lead to . . . How can schools expect that young people will find meaning in what they are doing if they so rarely draw their attention to considerations of the personal meaning and purpose of the work others do?
. . . most pervasive is a sense of emptiness that has ensnared many young people in long periods of drift during a time in their lives when they should be defining aspirations and making progress toward their fulfillment.
For too many young people today, apathy and anxiety have become the dominant moods, and disengagement or even cynicism has replaced the natural hopefulness of youth. That is not a problem that can be addressed by solutions advanced in the past. The message that young people do best when they are challenged to strive must be expanded to include an answer to the question: For what purpose? (ibid.)
This booklet was suggested by Brianne Blanton during her culminating oral examination for a master's degrees in educational administration at California State University-Bakersfield. Her husband, Peter, teaches algebra, and she had noticed that many students wanted to know "why?"
This booklet provides sample answers to first year algebra students who ask "why are we studying each of the California Algebra I Standards. It is written by graduate educational administration students who hope that it will be useful for algebra teachers.
1.0 Students identify and use the arithmetic properties of subsets of integers and rational, irrational, and real numbers, including closure properties for the four basic arithmetic operations where applicable.
A particle moved from an x-coordinate of 12 centimeters to an x-coordinate of 20 centimeters. At time T1 = 4 seconds and time T2 = 8 seconds. What is the average velocity?
20 – 12 = 8 = 2 cm/sec
8 - 4 4
1.1 Students use properties of numbers to demonstrate whether assertions are true or false.
Examples:
The sum of two even numbers will always be even.
2n + 2m = 2(n + m), which is always an even number if n and m are integers.
Multiplying two integers, the product is sometimes larger than the factors.
5 times 6 = 30: the product is larger than the factors.
-5 times 6 = -30: the product is smaller than either factor.
0 times 0 = 0: the product is equal to the factors.
8 2/3 times 3 1/2 has a product between 24 and 36, because 8 and 3 are less than 8 2/3 and 3 1/2, and 9 and 4 are greater than 8 2/3 and 3 1/2.
Applications:
Being able to quickly estimate a product is useful in bargaining and in recognizing mistakes.
In agriculture a farmer may face an aphid population that can double every three days. If the farmer did not recognize the mathematics of exponential growth, the farmer would fail to quickly respond to the aphid infestation. For example, assume that the farmer spots 20 aphids. Notice how fast this problem can spread over a 30 day period:
Aphids:
20

2.0Students understand and use such operations as taking the opposite, finding the reciprocal, taking a root, and raising to a fractional power. They understand and use the rules of exponents.
Therefore the actual weight can range between 4.75 pounds and 5.25 pounds.
4.0 Students simplify expressions before solving linear equations and inequalities in one variable, such as 3(2x-5) + 4(x-2) = 12.
Example:
3(2x – 5) + 4(x – 2)
=
12
6x – 15 + 4x – 8
=
12
Distributive law
6x + 4x – 15 – 8
=
12
Commutative law
10x - 23
=
12
Combining like terms
10x
=
12 + 23
Adding 23 to both sides
10x
=
35
Combining like terms
x
=
35/10 = 7/2
Multiplying both sides by 1/10
Applications:
(1) Let's say you only have $20.00 to spend on gas, and gas is $3.50 a gallon. How many gallons can you buy?
3.50x = 20.00, where x is the number of gallons one can purchase.
x = 5.71 gallons
(2) Let's say you have to move 2,500 miles across the country for a new job in Buffalo, New York. How much money do you need to save for gas, if the national average cost per gallon is $3.23 and your car gets 20 miles to the gallon?
(3) The oil refinery is equipped with a main pump that can fill the tank of an oil truck in 20 minutes, and an auxiliary pump which alone can fill the oil truck in 30 minutes. Sometimes it is necessary to fill the oil trucks faster to get them on the road, and so both pumps are used simultaneously. How much will that reduce the filling time?
If x is the number of minutes it takes to fill the tank with both pumps operating, then in one minute, both pumps can fill 1/x of the tank.
In one minute, the main pump can fill 1/20 of the tank. Similarly, in one minute, the auxiliary pump can fill 1/30 of the tank. With the two pumps running simultaneously, in one minute, the combined contribution of each pump will be
1/20 + 1/30 of the tank. This means that 1/20 + 1/30 = 1/x. Multiplying both sides by 60x, we get 3x + 2x = 60, or 5x = 60, or x = 12.
This means that there can be an 8 minute reduction over the 20 minute time it takes the main pump to fill an oil truck, if both pumps operate simultaneously.
5.0 Students solve multi-step problems, including word problems, involving linear equations and linear inequalities in one variable and provide justification for each step.
Example:
5x – 2y
=
7
x + 3y
=
15
6x + y
=
22
Adding the equations
y
=
22 – 6x
Subtracting 6x from both sides
5x – 2(22-6x)
=
7
Substituting y = 22 – 6x in the first equation.
5x – 44 + 12x
=
7
Using the distributive axiom.
17x
=
7 + 44
Using the commutative axiom, adding, and adding 44 to both sides
17x
=
51
Adding
x
=
3
Dividing both side by 17
y
=
22 – (6)(3) = 22 – 18 = 4
Substituting x = 3 in y = 22 – 6x.
Application:
A gas station charges $3.33 per gallon, and $5 for a car wash. If drivers fill-up their cars and get a car wash, the gas station reduces the charge per gallon of gas to $3.23 The gas station manager has noticed that this incentive motivates more drivers to get a car wash. Assume that the average motorist buys 12 gallons of gas per visit to the gas station, and that five out of a hundred motorists would also get a car wash without the advertised incentive. (A) Under those normal conditions, how much money does the gas station take in for every hundred motorists? (B) How many additional car washes would be necessary to at least break even, if gas is lowered by 10 cents a gallon?
Under normal conditions, this is how much money the gas station takes in per 100 motorists:
$3.33(12)(100) + $5(5) = $3,996 + $25 = $4,021
To calculate how many additional car washes it would take to make up the difference:
$3.23(12)(100) + $5(5 + x)
=
$4,021
$3,876 + 25 + 5x
=
$4,021
$3,901 + 5x
=
$4,021
5x
=
$120
x
=
$24
In other words, the number of car washes would have to increase from 5 to 24+5=29 out of every 100 motorists who utilized the gas station in order for this incentive to break even. More than 29 motorists would have to purchase car washes in order for this gas station to justify reducing the price of gasoline. Do you think that this incentive would work?

6.0 Students graph a linear equation and compute the x- and y-intercepts (e.g., graph 2x + 6y = 4). They are also able to sketch the region defined by linear inequality (e.g., they sketch the region defined by 2x + 6y < 4).
Example:

Graph 2x + 6y < 4
Start by graphing 2x + 6y = 4, as this graph represents all points on the line.
Now the graph of 2x + 6y < 4 will be on one side of the line or the other.
To determine which side, simply check out a point, such as (0,0) which is not on the line. Since (2)(0) + (6)(0) is less than 4, the graph of 2x + 6y < 4 will be on the "(0,0)" side of the line.
Application:
Greg's allowance is $5.00 a week if he does all his chores. Assuming Greg does his chores, graph how much allowance money Greg will have as the weeks go by, if he doesn't spend any of his allowance.

Application:
A carpenter wants to construct a simple cabin with a pitched roof. The inside height of this "A-frame" cabin next to the wall must be 8 feet high. The owner wants the inside height of the roof in the middle of the room (at the tallest point) to be 12 feet high. The owner wants the slope of the roof to be 1/3. How wide then must the cabin be?
Answer:
We know that the equation of a line, given the slope (m) and y-intercept (b), is:
y = mx + b. If we use the x-axis to represent the floor of the cabin, and the y-axis to represent a wall, then the y-intercept is (0, 8). The equation of the line then becomes:
y = (1/3)x + 8, and we want to know what x will be when y = 12.
Substituting in our equation:
14
=
(1/3)x +8
6
=
(1/3)x
18
=
x
This demonstrates that the roof will rise from 8 feet (next to the wall) to 14 feet in the center of room, which is 14 feet from the wall. The total width of the room would then be 28 feet—a very wide room.
How wide would the room be, if the highest point in the middle was 12 feet ? Experiment by changing the slope of the roof.
8.0 Students understand the concepts of parallel lines and perpendicular lines and how those slopes are related. Students are able to find the equation of a line perpendicular to a given line that passes through a given point.
Example:
For two lines to be perpendicular, the slope of one must be the negative reciprocal of the other. For example, consider the following two linear equations:
y=2x + 1 and y= -(1/2)x + 5
The slope of this line is 2. The slope of this line is –(1/2), the negative reciprocal of the first line.
Application: Why would anyone care if two lines were parallel ?
Gas mileage is affected by the tow of the car. Wheels that are not parallel will lower gas mileage and increase tire wear. Car owners who upgrade their suspension or lower their vehicle can use a simple, inexpensive technique to correct the toe of the wheels.
Start by running a string around the entire vehicle, making sure that the string crosses the vertical center of each wheel. The string should touch the front and back parts of all wheels. If not, the car is out of toe and the wheels are not parallel. If the string only touches the front or back portion of a wheel, adjustments can be made, depending on the make of the car.
The "camber" angle is the angle between the vertical reference (perpendicular to the road surface) and the line that runs through the center of the wheel. Zero camber indicates a wheel perpendicular to the road. Positive or negative camber negatively affects tire wear and car handling, causing the vehicle to pull left or right.
Specialized tools are needed to measure camber, although directions for homemade tools can be found on the internet. Camber can be adjusted following manufacturer's directions.
Other practical applications using parallel and perpendicular lines include road construction (most American towns are laid out with parallel and perpendicular lines), architectural design, railroad tracks, building frameworks, window panes and blinds, power lines, and the goal posts on a football field. The cross bar is perpendicular to the two outside posts.
9.0 Students solve a system of two linear equations in two variables algebraically and are able to interpret the answer graphically. Students are able to solve a system of two linear inequalities in two variables and to sketch the solution sets.
All of us are occasionally faced with a situation where we must choose between two payment methods for some service: Payment Method A requires an initial payment plus so much per month, versus Payment Method B requires no initial payment but a higher monthly rate. In such situations, Payment Method A is usually the better choice if one is going to continue purchasing the service for a long period of time. Payment B is better if one is only going to use the service for a short amount of time.
Let's examine a specific purchase, and determine the break-even point.
Businesses have website contracts with website hosting services to store and maintain computer files that make up their websites. Larry's Internet Provider Service charges a $10.00 set up fee plus $21.95 per month. Ajax Website Hosting, Inc. charges $22.45 per month, but without a set up fee. Let's find the break-even point.
Solution:
Let y be the total cost after x months.
Larry's Internet Provide Service costs = y = 10 + 21.95 x
Ajax Website Hosting, Inc. costs = y = 22.45 x
To solve these two simultaneous linear equations, we substitute 22.45x for y in the first equation: 22.45 x = 10 + 21.95 x Subtracting 21.95x from both sides, we get:
.5 x = 10 or x = 20. This means that by month 20, the total cost one would have spent on the two services over 20 months would have been the same.
In month 18:
y = 10 + (21.95)(18) = 10 + 395.10 = 405.10
Larry's Internet
y = (22.45)(18) = 404.10
Ajax Website Hosting
In month 19:
y = 10 + (21.95)(19) = 10 + 417.05 = 427.05
Larry's Internet
y = (22.45)(19) = 426.55
Ajax Website Hosting
In month 20:
y = 10 + (21.95)(20) = 10 + 439 = 449.
Larry's Internet
y = (22.45)(20) = 449.
Ajax Website Hosting
In month 21:
y = 10 + (21.95)(21) = 10 + 460.95 = 470.95
Larry's Internet
y = (22.45)(21) = 471.45
Ajax Website Hosting
In month 22:
y = 10 + (21.95)(22) = 10 + 482.90 = 492.90
Larry's Internet
y = (22.45)(22) = 493.90
Ajax Website Hosting
Now one might conclude that it doesn't make much difference which payment method is chosen, and it only makes a dollar difference by month 22. However, consider the difference after five years or 60 months:
y = 10 + (21.95)(60) = 10 + 1317 = 1327.00
y = (22.45)(60) = 1347
Now there is a $20. difference.
How much difference would there be after ten years?
y = 10 + (21.95)(120) = 10 + 2634 = 2644
y = (22.45)(120) = 2694
There would be a $50 difference in the amount spent.
10.0 Students add, subtract, multiply, and divide monomials and polynomials. Students solve multi-step problems, including word problems, by using these techniques.
Example:
(x2 + 13x + 46) + (x2 + 7x + 10) = 2x2 + 20x +56
Applications:
You are putting a stone border (of the same width) along the front and an adjacent side of a rectangular garden that measures six yards by fifteen yards. You have only enough stone to cover 46 square yards. How wide should the border be?
Solution:
Area of Border = Total Area – Area of Garden
46
=
(x + 15)(x + 6) – (15)(6)
46
=
(x2 + 6x + 15x + 90) – 90
46
=
(x2 + 21x + 90) – 90
46
=
x2 + 21x
0
=
x2 + 21x – 46
0
=
(x + 23) (x – 2)
x + 23 = 0
or
x – 2 = 0
x = -23
or
x = 2
While the solutions are -23 and 2, only x = 2 is a reasonable solution, because negative values for dimension don't make sense. Hence the border should be 2 yards wide.
How many miles would someone who purchased a $45,000 car that gets 45 miles to the gallon have to drive to come out even with the individual who purchased a car for $35,000 which gets 35 miles to the gallon? Assume that gas costs $3 per gallon.
$45,000 + 3(d/45) =
$35,000 + 3(d/35)
We want to know what d will be when the two sides of the equation will be equal
10,000 =
(3d/35) - (3d)/45)
10,000 =
135d - 105d

11.0 Students apply basic factoring techniques to second- and simple third-degree polynomials. These techniques include finding a common factor for all terms in a polynomial, recognizing the difference of two squares, and recognizing perfect squares of binomials.
Example:
x2 + 2x – 15 = 0 (Notice that the first term is of the 2nd degree, and the second term is of the first degree. This a 2nd degree equation.)
(x – 3)(x + 5) = 0 (Factoring)
x – 3 = 0 and/or x + 5 = 0
x = 3 x = -5
Application:
A ball is thrown upward with an initial velocity of 40 feet per second, and the distance from the starting point is given by the formula d = 40t -16t2.
Notice that at a half-second, the ball will be 40(.5)-16(.5)2=20-4=16 feet high.
After one second, the ball will be 40(1)-16(1)2=40-16=24 feet high.
After one and a quarter seconds, the ball will be 40(1.25)-16(1.25)2=25 feet high.
After one and a half seconds, the ball will be 40(1.5)-16(1.5)2=24 feet high.
13.0 Students add, subtract, multiply, and divide rational expressions and functions. Students solve both computationally and conceptually challenging problems by using these techniques.
Example:
Divide 8a2 – 15ab + 7b2 by a – b.
8a2 – 15ab + 7b2 = (8a – 7b)(a - b)
Hence, the answer is 8a – 7b.
Applications:
Much of the world measures temperature using the Centigrade thermometer, rather than the Fahrenheit scale. One can use the following conversion formula to change Fahrenheit to Centigrade: TC = (5/9) (TF -32)
When the Fahrenheit temperature in Los Angeles, California is 77 degrees, what is the equivalent Centigrade temperature?
Two girls, Oralia and Teresa, are balanced on a seesaw. The girls find that they must sit at distances from the support such that the products obtained by multiplying the weight of each by her distance from the fulcrum, or point of support, are equal.
Oralia weighs 85 pounds, and Teresa weighs 100 pounds. Oralia is seated 8 feet from the fulcrum. How far is Teresa sitting from the fulcrum?

Application:
A manager of an apartment house complex is deciding how much monthly rent to charge for each of the 60 newly built units. He has been charging $950 per month, and all 60 apartments have been occupied. He has found that for every additional $25 per month he charges, one apartment is likely to remain vacant. However, since service and maintenance costs are higher for occupied apartments than for vacant ones, he figures he can increase his profit margin by raising the monthly rental and still collect the same total rental of $47,000. The question he must answer is, how much should he charge and how many apartment units would then likely remain vacant at the higher rent?
He starts by letting x represent the number of vacant apartment units, so that 60-x will represent the number of occupied apartment units.
The amount of total rent he wants to obtain is $57,000. Hence, the number of occupied apartment units times the amount he will be charging must equal $57,000.
Hence, $57,000 = (60 – x)($950 +$25x) Explantion: remember that for every vacant unit he has raised the rent $25. Hence, if he raises the rent $150 = (3)(25), he would only have 60 – 3 = 57 rented apartments.)
Hence, when all of the apartments are rented (x = 0),
the total rent is $57,000.
However, the apartment owner can realize the same total
and increase his profit margin by raising the monthly rental
per unit to $950 + (22)($25) = $1500, with 22 vacant units.
What quantities of silver 60% and 82% pure must be mixed together to give 12 ounces of silver 70% pure?
Let x = the number of ounces of 60% pure silver.
Let y = the number of ounces of 82% pure silver.
The total amount of x + y = 12 ounces.
Now .60x will be the actual amount of silver in the "60% type," and
.82y will be the actual amount of silver in the "82% type."
Hence, .60x + .82y = (.70)(12), since (.70)(12) will be the actual amount of silver in the total mixture.
With this information we can solve the two simultaneous equations:
.60x + .82y = (.70)(12) x + y = 12
.60x + .82y = 8.4
x + y = 12
.60x + .82y = 8.4 .60x + .60y = 7.2 (Multiplying both sides by .60)
.22y = 1.2 (Subtracting )
y = 5 5/11
x + 5 5/11 = 12 x = 6 6/11
16. Students understand the concepts of a relation and a function, determine whether a given relation defines a function, and give pertinent information about given relations and functions.
Any set of ordered pairs is a relation. Thus, (2, 5), (2, 6) and (2, 7) could define a relation. However, that relation is not a function, because a function is a single-valued relation. For every first value, a function specifies a specific second value—not three, as in the above mentioned relation.
Example:
This is an important distinction. For example, suppose that we wish to purchase three hamburgers, each of which costs $1.50. Multiplying 3 times $1.50 = $4.50 The result can be written as (3, $4.50). Here, if the customer knows how many hamburgers he or she is purchasing, there is one total purchase price. We say that the total purchase price, P, is a function of the number of hamburgers purchased f(h). This can also be written: P =f(h) In this example, f(h) = $1.50 times h, or $1.50 h.
Application:
A rental company charges $50 plus $42 per day to rent 100 chairs for a wedding. Write a function to represent this situation, and calculate how much it will cost to rent the chairs for three-days.
In this situation, the total cost, C, of renting the chairs will depend upon how many days, d, they will be needed, plus $50. Hence, C is a function of d plus $50. This can be written: C = f(d) + 50. In this case, f(d) = $42 times d, or $42 d.
If we wish to rent the chairs for three days, f(d) = $42 times 3 = $126. But then we need to remember that there is a $50 fee, regardless of how many days we rent the chairs. Hence, C = f(d) + $50 = $126 + 50 = $176.
Application:
Sometimes costs will depend upon two functions. For example, when renting a truck, the cost might depend upon the number of days rented and the number of miles driven.
Let's say a rental company charges $34 per day and 23 cents per mile. The cost (C) will then be a function of both the number of days (d) the truck is rented, and the number of miles (m) the truck is driven. We can write that as: C = f1(d) + f2(m)
In this case f1(d) = $34d and f2(m) = .23m
Let's assume that we will need to truck for 2 days and we drove it 250 miles. We can then calculate our total cost as:
Newly hatched channel catfish typically weigh about 0.06 grams. During the first six weeks of life their weight increases by about 10% each day. The following exponential mathematical model describes their growth:
y = C(1 + r)t where y is the weight of the catfish after so many days (t); C is the initial weight in grams; and r is the growth rate.
After one week, or 7 days, their weight is:
y = 0.06(1 +0.10)7
y = 0.12 grams
Assume that you purchased a $25,000 car. It is expected to lose value or depreciate at the rate of 12% per year. The following exponential mathematical model describes what
the car will be worth after t years:
y = C (1 – r)t where y is the value of the car after t years; C is the initial value of
the car; and r is the rate of depreciation.
Let's examine what the car will be worth after 10 years:
y = 25,000(1 - .12)10
y = 25,000(.2785) = $6,962.50
17.0 Students determine the domain of independent variables and the range of dependent variables defined by a graph, a set of ordered pairs, or a symbolic expression.
Example:
Find the domain of y = 2√x
Use several values in the domain to make a table of values for the function.
Solution:
Since the square root is defined only when x, in this case, is non-negative, the domain of y = 2√x consists of all non-negative numbers.

Application:
The production of corn is sometimes a profitable business, depending upon the weather and how much it costs to bring the corn to market. According to Iowa State University, the amount of corn grown per acre depends upon the seeding rate.
Based upon this research, Iowa State believes that the best seeding rate for corn is about 35,000 seeds per acre.
What is the domain and range represented by the above graph?
{Domain: 20,000 to 45,000 plants per acre}
{Range: 77% to 100% of maximum yield}
Corn seed prices are about $1.30 per 1,000 seed. The corn grain market price is about $3.00 per bushel. (A bushel is 56 pounds.) Corn farmers produce about 200 bushels of corn per acre.
How much would 35,000 seeds cost? {$45.50} How much does 200 bushels of corn sell for? {$600.00} What other costs will a corn farmer face? {planting, weed control, pest management, harvesting, transportation to market.}
18.0 Students determine whether a relation defined by a graph, a set of ordered pairs, or a symbolic expression is a function and justify the conclusion.
If no two ordered pairs in a relation have the same first component and different second componets, then the relation is called a function. Graphically, this means that no vertical line will interest the graph at more than one point.

19.0 Students know the quadratic formula and are familiar with its proof by completing the square.
Tom (T) can paint a building in 5 days less than the time it takes Jim (J). Working together, they can complete the work in 6 days. How long does it take each to do the job alone?
Of these two solutions, the only one that makes sense is that Tom takes 10 days, since he couldn't take a negative amount of time. Therefore, Jim would take 15 days.
20.0 Students use the quadratic formula to find the roots of a second-degree polynomial and to solve quadratic equations.
Example:
Solve, using the quadratic formula: 2x2 – 6x – 9 = 0
Using the quadratic formula, a=2, b=-6, and c=-9.

Application:
The distance s a body falls in a vacuum is given by s = v0t + (1/2)gt2,
where s is in feet, t is in seconds, v0 is the initial velocity in feet per second,
and g is the constant of acceleration due to gravity (approximately 32 ft/sec/sec).
How long will it take a body to fall 150 feet if v0 is 20 feet per second?
A car with an initial velocity of 30 meters per second begins to accelerate at a constant rate of 2.8 meters per second. How long does it take the car to travel 200 meters?
200 = 0 + 30t + (1/2)(2.8)t2
0 = 1.4t2 + 30t – 200
t = -30 ± √ [(30)2 – (4)(1.4)(-200)]

24.0 Students use and know simple aspects of a logical argument.
Explanation:
Logical arguments involve:
1. Figuring out what is known;
2. Thinking about what is known means, includes, and/or implies; and
3. Determining whether a conclusion can be reached which is a part of what is known.
Application:
Consider offers made by three different cell phone providers. All of the providers advertise their plan for $69.99 a month with 700 minutes of talk time.
The first provider ABC has a family share plan that includes two lines. This plan requires a minimum of two lines, but this number can be increased up to a maximum of five lines, with each additional line costing $9.99 per month. The ABC package also includes:
700 rollover minutes to share
Unlimited night and weekend minutes
Unlimited mobile-to-mobile minutes
Free long distance and free roaming on the ABC network!
The second provider Sprung has a family share plan that includes two lines. This plan requires a minimum of two lines, but this number also be increased up to a maximum of five lines. Each additional line costs $9.99 per month. The Sprung package also includes:
700 anytime minutes to share
Unlimited mobile-to-mobile minutes
Unlimited night and weekend minutes starting at 7 p.m.
Nationwide long distance and no roaming charges
The third provider Horizon has a family share plan that includes one line. This plan requires a minimum of two lines and can have up to a maximum of five lines. Each additional line costs $9.99 per month. The Horizon package also includes:
700 shared minutes
Unlimited night and weekend airtime minutes
Unlimited IN Calling (All lines)
Free roaming and long distance on their nationwide network
To select the best plan for your family use a logical argument, first figuring out what is known.
At this point, you know what the three companies offer, but don't forget what you want. Let's assume that you have budgeted $75.00 a month for cell phones, and need two.
Based upon your past history, you recall that your family uses their cell phones about 700 minutes a month, and frequently talk throughout the day to family members who live elsewhere in California.
With that information about what is known, your family needs to examine the meaning of each plan for your family's situation.
Since Horizon offers a family share plan with 700 shared minutes that is offered for $69.99 a month, it is within our budget for cell phone coverage. However, Horizon would require us to have two lines, and the plan only covers one line. Since each additional line costs $9.99 a month, the real price for Horizon would be $79.98, which is more than our budget will allow. Hence, since this is more than we want to spend on cell phones, we definitely need to consider the other two plans.
Since Sprung has a plan for $69.99 a month with 700 minutes including two lines, the Sprung plan is within our budget. Their unlimited mobile-to-mobile and nationwide long distance service is appealing, but their unlimited night and weekend minutes does not start until 7 p.m. This is a decided drawback to us, because we would like to speak with family members at any time, and not have to wait until after 7 p.m. without incurring an additional fee. Hence, while the Sprung plan better meets our needs than the Horizon plan, we proceed to consider the ABC plan.
The ABC plan costs $69.99 a month with 700 minutes including two lines, and that is within our budget. The ABC plan would allow us to share the minutes, and if we don't use them they would rollover to another month. Further, they have unlimited nights and weekends, without having to wait until after 7 p.m., and free long distance. Therefore, the ABC plan includes everything that we sought in a cell phone service package. Hence, our family concludes that we should select the ABC plan.
24.1 Students explain the difference between inductive and deductive reasoning and identify and provide examples of each.
Example:
Inductive reasoning is the process of reaching a conclusion about the truth of a statement by making use of observations. Theories in science are based upon inductive reasoning. Scientific theories consist of statements about what is expected to happen in cases similar to other observations.
For example, Galileo rolled a ball down an inclined track and measured how fast it traveled. Using his pulse to measure time, he noticed that the ball proceeded down the track in proportional units to the square of the time, as shown in the following table:
Pulse: 1 2 3 4 5 6 …
Distance: 1 4 9 16 25 36 …
While Galileo couldn't check out all situations, he used inductive reasoning to reach the above conclusion, based upon his observations.
Deductive reasoning begins with statements accepted without proof. These statements are called axioms. When we use deductive reasoning, we must show that the statement we are trying to prove is a subset of the axioms. For example, in ordinary arithmetic with the set of natural numbers, the axiom or law of trichotomy is accepted without proof. The law of trichotomy says that exactly one of the following is true: a = b; or a = b plus a natural number; or a plus a natural number = b.
Using deductive reasoning we can prove that all positive even natural numbers a=b; a=b+r; or a+r=b, where r is a natural number. Since the positive even natural numbers are a subset of all natural numbers, and since that law of trichotomy holds for all natural numbers, the proposition holds for all positive even natural numbers.
Application:
While scientific theories are based upon observations, Goldbach used inductive reasoning to discover a theory in mathematics. Goldbach observed that every even integer greater than 4 is the sum of two odd primes. While no one has been able to find a counter-example, no one has been able to deductively prove that this observation discovered inductively is always true.
24.2 Students identify the hypothesis and conclusion in logical deduction.
The hypothesis of a statement includes all that is assumed, in order to reach the conclusion. A hypothesis is often identified by the qualifier "if." If … the hypothesis … , then …. the conclusion.
Example:
Hypothesis: If two integers are both odd,
Conclusion: Then their product will be odd.
Proof: Let A and B be any two odd integers.
A and B can be written as 2n – 1 and 2m – 1, because this is the definition of an
odd integer, where n and m are integers.
(2n – 1) (2m – 1) = 4nm – 2n – 2m + 1 = 2(2nm – n – m) + 1
Since 2(2nm – n – m) is an even number, based on the definition of even
numbers, adding one to an even number will always produce an odd number.
Therefore, if A and B are odd integers, the product AB will be an odd integer.
Decision-making Application:
A man walks up a restaurant counter where there are three seated customers. Though he had never seen any of them before, he had previously learned that one of them was a used car salesman who was unable to make a truthful statement, one was an attorney who shuffled truth and falsehood so thoroughly that one could never be sure that a given statement of his was true or false, and the other invariably told the truth—an inconvenient trait that made him unemployable.
The man hoped by questioning them to identify each with his occupation. He sat down to the left of the group and ordered a milkshake. Then he turned to the man beside him and asked of him the occupation of the man in the middle. He was told that he sold used cars. Then he spoke to the man in the middle and asked him directly about his occupation.
After he thought about the middle man's reply, he finished his milkshake and left, having determined the trade of each of the men.
What did each do?
(Notice that all of the foregoing information is a hypothesis. We are now asked to determine what conclusions we can logically draw from that information.)
Solution:
Let's call the used car salesman: "U"
the attorney: "A," and
the 3rd man: "T" for truthful.
The first man he asked either told the truth or didn't tell the truth. If he didn't tell the truth, he was either the used car salesman (U) or the attorney (A). If he did tell the truth, he must have been the third man (T).
Let's assume he was T, having told the truth. When the middle man was spoken to, if he said he was an attorney (not telling the truth if this scenario is correct), then we would know that the men were: T, U, and A.
Again, assuming that the first man told the truth, and the middle man said he was a used car salesman, we would know that the first man was not T, because T always tells the truth and U doesn't.
Now, let's assume that the first man didn't tell the truth. Then the first man must be U, because A wouldn't have given any information. If he is U, then the middle man must either be A or T. If the middle man is A, once again, in speaking with him we will see that we can't get any information, so the men must be: U, A, and T. If the middle man is determined not to be A, he must be T. So the men must be: U, T, and A.
A Criminal Justice Application:
When investigating a crime scene, a detective has to make hypotheses about what has occurred. The detective looks for clues and evidence that either supports or refutes their hypotheses, which change as more information becomes available.
Here is what a detective found at a crime scene:
A discharged weapon lying by a deceased male victim.
Blood splatter on the north wall and on a chair located in the southeast corner.
A pool of blood under and around the deceased victim.
3 bullet holes in the north wall, with 2 bullets still in the wall.
2 bullet wounds in the deceased victim.
A ring line and a watch line on the victim, but no watch or ring can be located.
The victim's wallet is missing.
Lab Results:
No fingerprints were found beside the victim's.
No powder residue was found on the deceased victim.
The bullet entry wounds came from two different angles.
The blood on the couch belongs to another male individual, but his DNA is not in police databases.
The detective's hypothesis: A murder has been committed.
Supporting evidence:
A person committing suicide would not be able to shoot themselves twice without leaving residue powder on their hands. They also would not have missed one time if they were shooting themselves. A robbery also seems to have occurred, since a wallet and jewelry are missing. A second party was involved because of the blood on the couch which points to a murder suspect.
24.3 Students use counterexamples to show that an assertion is false and recognize that a single counterexample is sufficient to refute an assertion.
Now suppose that one discovered Legendre's formula, and tried it out for n=1, n= 2, n=3, n=4, n=5, and for a few more. One might easily conclude that this formula would always produce prime numbers. However, all one needs to show is one counterexample to prove that Legendre's formula does not always produce prime numbers.
Prove: If a number (n) is not evenly divisible by 3, then n2 – 1 is evenly divisible by 3.
All numbers (integers) are of the form n, n+1, and n+2.
The above proposition pertains to those numbers that are not evenly divisible by
Therefore, these other numbers must be of the form n+1 and n+2.
In other words, if n is divisible by 3, then n+1 and n+2 are not, and we want to prove that when these other numbers of the form (n+1) and (n+2) are squared and
1 is subtracted, that the result will always be evenly divisible by 3.
So, we examine what happens when these other numbers are written in the form
n2 – 1:
25.3 Given a specific algebraic statement involving linear, quadratic, or absolute value expressions or equations or inequalities, students determine whether the statement is true sometimes, always or never.
Example:
Let's define the "square of the opposite" of a rational number, x, as (-1)x2
Which, if any, of the following statements is true?
The square of the opposite of a rational number, x, is less than to x.
The square of the opposite of a rational number, x, is more than x.
The square of the opposite of a rational number, x, is sometimes equal to x.
The square of the opposite of a rational number, x, is sometimes more and sometimes less than x.
Answer:
Consider numbers on the rational number line:
If x=2, then (-1)x2=-4.
If x=1, then (-1)x2=-1.
If x=1/2, then (-1)x2=-(1/4).
If x=0, then (-1)x2=0.
If x=-(1/2), then (-1)x2=-(1/4).
If x=-1, then (-1)x2=-1.
If x=-2, then (-1)x2=-4.
Notice that rational numbers larger than 2 will behave like 2, and that rational numbers smaller than -2 will behave like -2.
Hence, if x is greater than 0, (-1)x2 will be smaller than x.
If x=0, (-1)x2 = 0.
If x is less than 0 but greater than -1, (-1)x2 will be larger than x.
If x=-1, then (-1)x2 will be equal to x.
If x is less than -1, (-1)x2 will be less than x.
Therefore, answers C and D are correct.
Application:
Graph the equation: y = (-1) x2

Note: Underwood Dudley argues in a recent article ("What Is Mathematics
For?") in the Notices of the American Mathematical Society (Vol. 57, Num.
5, May 2010, 608-613) that mathematics "is needed very, very seldom, and we do
not need to train millions of students in it to keep businesses going." He
says that while mathematics "is the most glorious creation of the human
intellect," "what mathematics education is for ... [is] to teach reasoning,
usually through the medium of silly problems." | 677.169 | 1 |

A huge new point of view on AFFINE AND PROJECTIVE GEOMETRYThis leading edge booklet treats math majors and math schooling scholars to a clean examine affine and projective geometry from algebraic, artificial, and lattice theoretic issues of view.Affine and Projective Geometry comes entire with 90 illustrations, and diverse examples and routines, masking fabric for 2 semesters of upper-level undergraduate arithmetic. the 1st a part of the ebook offers with the correlation among man made geometry and linear algebra. within the moment half, geometry is used to introduce lattice conception, and the ebook culminates with the elemental theorem of projective geometry.While emphasizing affine geometry and its foundation in Euclidean strategies, the ebook: * Builds an appreciation of the geometric nature of linear algebra * Expands scholars' realizing of summary algebra with its nontraditional, geometry-driven method * Demonstrates how one department of arithmetic can be utilized to turn out theorems in one other * presents possibilities for additional research of arithmetic via numerous ability, together with ancient references on the ends of chaptersThroughout, the textual content explores geometry's correlation to algebra in ways in which are supposed to foster inquiry and boost mathematical insights even if one has a historical past in algebra. The perception provided is especially very important for potential secondary lecturers who needs to significant within the topic they train to meet the licensing standards of many states. Affine and Projective Geometry's wide scope and its communicative tone make it a terrific selection for all scholars and execs who want to extra their knowing of items mathematical.
Self-similarity is a profound idea that shapes a few of the legislation governing nature and underlying human notion. it's a estate of common medical value and is on the centre of a lot of the new paintings in chaos, fractals, and different components of present study and renowned curiosity. Self-similarity is expounded to svmmetry and is an characteristic of many actual legislation: particle physics and people governing Newton's legislation zero , gravitation.
This ebook is a revised and increased new version of the 1st 4 chapters of Shafarevich's recognized introductory booklet on algebraic geometry. along with correcting misprints and inaccuracies, the writer has further lots of new fabric, more often than not concrete geometrical fabric akin to Grassmannian types publication assumes purely common algebraic wisdom (rings, modules, teams, Lie algebras, functors and so forth. ). it's worthy, besides the fact that, to grasp a few fundamentals of algebraic geometry and illustration idea.
For k > 2 there is a partial affine plane of order η with k pencils of parallel lines if and only if there are k - 2 mutually orthogonal Latin squares of order n. Proof: The proof follows from the same construction as was done for Theorem 9. • Corollary. The finite partial affine planes of order η having four pencils of parallel lines correspond to the pairs of orthogonal Latin squares A and Β of order n. Thus the open question stated above can be rephrased in terms of affine geometry: Is there a partial affine plane of order 10 with 5 pencils of parallel lines?
Suppose that A and Β are orthogonal Latin squares of order η and that J and Κ are constant η Χ η matrices with entries j and k, respectively. Prove that A + J and Β + Κ are orthogonal Latin squares (again the addition should be done mod «). 5. Suppose that A and Β are orthogonal Latin squares of order n, and that k in Z" is relatively prime to n. Show that A and kB are orthogonal Latin squares, where the (/th entry in kB is x " b , . 6. Let π be an odd natural number. Show that A = [β"] and fi = [fc,--] are orthogonal Latin squares of order /j where ; and 2 / + / - 1.
In this language it was already seen that H(2) = H(6) = 1 and that H(n) ^ 2 otherwise. Results on affine planes in Chapter 4 will imply that whenever ρ is a prime number, H(p ) = p - 1. The connection between pencils of parallel lines and Latin squares is summarized in the following theorem: k k • THEOREM 9. For η :> 2, there is an affine plane of order η if and only if / / ( « ) > η - 1. Proof: Given an affine plane of order n, select two of its (n + 1) pencils of parallel lines, and denote them by Γ, and Γ . | 677.169 | 1 |

The goal of this text is to help students leam to use calculus intelligently for solving a wide variety of mathematical and physical problems. This book is an outgrowth of our teaching of calculus at Berkeley, and the present edition incorporates many improvements based on our use of the first edition. We list below some of the key features of the book. Examples and Exercises The exercise sets have been carefully constructed to be of maximum use to the students. With few exceptions we adhere to the following policies. • The section exercises are graded into three consecutive groups: (a) The first exercises are routine, modelIed almost exactly on the exam pIes; these are intended to give students confidence. (b) Next come exercises that are still based directly on the examples and text but which may have variations of wording or which combine different ideas; these are intended to train students to think for themselves. (c) The last exercises in each set are difficult. These are marked with a star (*) and some will challenge even the best students. Difficult does not necessarily mean theoretical; often a starred problem is an interesting application that requires insight into what calculus is really about. • The exercises come in groups of two and often four similar ones.
This fifth edition of Lang's book covers all the topics traditionally taught in the first-year calculus sequence. Divided into five parts, each section of A FIRST COURSE IN CALCULUS contains examples and applications relating to the topic covered. In addition, the rear of the book contains detailed solutions to a large number of the exercises, allowing them to be used as worked-out examples -- one of the main improvements over previous editions.
With a fresh geometric approach that incorporates more than 250 illustrations, this textbook sets itself apart from all others in advanced calculus. Besides the classical capstones--the change of variables formula, implicit and inverse function theorems, the integral theorems of Gauss and Stokes--the text treats other important topics in differential analysis, such as Morse's lemma and the Poincaré lemma. The ideas behind most topics can be understood with just two or three variables. The book incorporates modern computational tools to give visualization real power. Using 2D and 3D graphics, the book offers new insights into fundamental elements of the calculus of differentiable maps. The geometric theme continues with an analysis of the physical meaning of the divergence and the curl at a level of detail not found in other advanced calculus books. This is a textbook for undergraduates and graduate students in mathematics, the physical sciences, and economics. Prerequisites are an introduction to linear algebra and multivariable calculus. There is enough material for a year-long course on advanced calculus and for a variety of semester courses--including topics in geometry. The measured pace of the book, with its extensive examples and illustrations, make it especially suitable for independent study.
For over three decades, this best-selling classic has been used by thousands of students in the United States and abroad as a must-have textbook for a transitional course from calculus to analysis. It has proven to be very useful for mathematics majors who have no previous experience with rigorous proofs. Its friendly style unlocks the mystery of writing proofs, while carefully examining the theoretical basis for calculus. Proofs are given in full, and the large number of well-chosen examples and exercises range from routine to challenging. The second edition preserves the book's clear and concise style, illuminating discussions, and simple, well-motivated proofs. New topics include material on the irrationality of pi, the Baire category theorem, Newton's method and the secant method, and continuous nowhere-differentiable functions.
This new, revised edition covers all of the basic topics in calculus of several variables, including vectors, curves, functions of several variables, gradient, tangent plane, maxima and minima, potential functions, curve integrals, Green's theorem, multiple integrals, surface integrals, Stokes' theorem, and the inverse mapping theorem and its consequences. It includes many completely worked-out problems.
Burstein, and Lax's Calculus with Applications and Computing introduction to probability and information theory.
This self-contained textbook gives a thorough exposition of multivariable calculus. The emphasis is on correlating general concepts and results of multivariable calculus with their counterparts in one-variable calculus. Further, the book includes genuine analogues of basic results in one-variable calculus, such as the mean value theorem and the fundamental theorem of calculus. This book is distinguished from others on the subject: it examines topics not typically covered, such as monotonicity, bimonotonicity, and convexity, together with their relation to partial differentiation, cubature rules for approximate evaluation of double integrals, and conditional as well as unconditional convergence of double series and improper double integrals. Each chapter contains detailed proofs of relevant results, along with numerous examples and a wide collection of exercises of varying degrees of difficulty, making the book useful to undergraduate and graduate students alike.
This book presents first-year calculus roughly in the order in which it was first discovered. The first two chapters show how the ancient calculations of practical problems led to infinite series, differential and integral calculus and to differential equations. The establishment of mathematical rigour for these subjects in the 19th century for one and several variables is treated in chapters III and IV. Many quotations are included to give the flavor of the history. The text is complemented by a large number of examples, calculations and mathematical pictures and will provide stimulating and enjoyable reading for students, teachers, as well as researchers.
From the reviews "This is a reprint of the original edition of Lang's 'A First Course in Calculus', which was first published in 1964....The treatment is 'as rigorous as any mathematician would wish it'....[The exercises] are refreshingly simply stated, without any extraneous verbiage, and at times quite challenging....There are answers to all the exercises set and some supplementary problems on each topic to tax even the most able." --Mathematical Gazette
This text is intended for an honors calculus course or for an introduction to analysis. Involving rigorous analysis, computational dexterity, and a breadth of applications, it is ideal for undergraduate majors. This third edition includes corrections as well as some additional material. Some features of the text include: The text is completely self-contained and starts with the real number axioms; The integral is defined as the area under the graph, while the area is defined for every subset of the plane; There is a heavy emphasis on computational problems, from the high-school quadratic formula to the formula for the derivative of the zeta function at zero; There are applications from many parts of analysis, e.g., convexity, the Cantor set, continued fractions, the AGM, the theta and zeta functions, transcendental numbers, the Bessel and gamma functions, and many more; Traditionally transcendentally presented material, such as infinite products, the Bernoulli series, and the zeta functional equation, is developed over the reals; and There are 385 problems with all the solutions at the back of the text. | 677.169 | 1 |
Governor's School 2003 - Mathematics Elective
Patterns
Do you see the patterns in all the things around you? Would you
like to know how to describe, study and create these patterns?
In this course, we will study the mathematics of patterns. We'll
start with descriptions of patterns in sequences of numbers and in
geometric designs. We'll study the properties of these patterns
and then we will begin to apply what we've learned to study and create
various patterns. As we study tilings, chaos and the stock market!?,
we'll try to see if mathematics can show us something useful about
these patterns.
The course will be a mix of theory, computation (by hand and by computer)
and experimentation. You should have good algebra and general math
and problem solving skills. If you know more math, we'll use more,
but we'll develop most of the mathematics we need as we need it. We'll
also be using computers to work out some examples and solve some problems.
However, no programming experience is necessary, unless you want to write
your own programs.
Course Instructor: Dr. Charles R. (Chuck) Collins (B.S., Texas A&M University;
Ph.D., University of Minnesota) is an Associate Professor of
Mathematics at UT, where he teaches a wide range of courses from Calculus to
graduate level seminars in Numerical Analysis. His main focus is on
developing mathematical models of real-world situations and then
determining how to best solve the resulting problem efficiently on a computer. | 677.169 | 1 |

This book uses Matlab as an aid to learning and understanding basic circuit analysis. Most introductory texts on circuit theory introduce Ohm':s law and Kirchhoff':s law very quickly and are then off to the races. This book spends a fair amount of time in Chapter 1 putting these laws and other basic concepts in a historical perspective. This will provide you with the knowledge of where the basic ideas of electrical science come from. Chapter 2 discusses circuit elements including resistors, capacitors, and inductors. Ohm's law is covered in Chapter 2 and Kirchhoff's law's are described in Chapter 3. Sinusoidal signals and phasors are introduced in Chapter 4 where the concept of RMS values are described. This allows both DC and steady-state AC circuits to be solved in subsequent chapters. Examples involving voltage dividers, current division, and source transformation are given in Chapter 5. Circuits that include an ideal operational amplifier (op amp) are described in Chapter 6. Mesh and nodal analysis are covered in Chapter 7 where you will learn to do mesh and nodal analysis by inspection. Chapter 8 covers superposition, Thevenin's theorem, Norton's theorem, and maximum power transfer. Average power and transformers are covered in Chapter 9 and the theory behind the operation of DC motors is given in Chapter 10. Basic material on vectors and matrices are included in the Appendices. By restricting the analysis of AC circuits to sinusoidal signals, no knowledge of differential equations is required. All circuit problems in this book contain only independent voltage and current sources. All worked examples in the book show the calculations using Matlab. In most cases Matlab is used as a calculator and a good scientific calculator could be used to solve most of the examples. The use of Matlab clarifies all of the steps. However, Matlab is also used to create a variety of plots that will help you understand the material.

This introductory book emphasizes algorithms and applications, such as cryptography and error correcting codes, and is accessible to a broad audience. The presentation alternates between theory and applications in order to motivate and illustrate the mathematics. The mathematical coverage includes the basics of number theory, abstract algebra and discrete probability theory. This edition now includes over 150 new exercises, ranging from the routine to the challenging, that flesh out the material presented in the body of the text, and which further develop the theory and present new applications. The material has also been reorganized to improve clarity of exposition and presentation. Ideal as a textbook for introductory courses in number theory and algebra, especially those geared towards computer science students.
Reviews:
"The subject matter is presented in a very thorough way. Detailed and clear proofs are given for (almost) all results. The material is very well organized: definitions, results, and their interrelations fit together perfectly. The book is especially attractive to students with a background or interest in computer science. On the other hand, students who already have a background in abstract algebra can benefit greatly from this book by skipping some parts where algebraic theory is introduced. The suitability of the book for self-study is greatly enhanced by a wealth of exercises and examples that are provided. Last but not least, the book is very well-written, and it is a pleasure to read.
Gregor Kemper, Mathematics of Computation
"It's a pleasure to find a book that is so masterful and so well written that it has all the
hallmarks of a classic. This is such a book.This is a truly magnificent text, deserving of a place on the shelves of any mathematician or computer scientist working in these areas."

Does someone here know anything about daily math trivia ? I'm a little lost and I don't know how to answer my math project about this topic. I tried researching all tutorials about it that could help me answer my math problems but I still can't finish it. I'm having a hard time understanding it especially the topics inverse matrices, adding numerators and interval notation. It will take me forever to answer my math homework if I can't get any assistance. It would really help me if somebody would recommend anything that can help me with my algebra homework.
Well I do have a advice for you.There used to be time when even I was stuck on problems relating to daily math trivia , that's when my elder sister suggested that I should try Algebra Helper . It didn't just solve all my queries, but it also explained those answers in a very nice step-by-step manner. It's hard to believe but one night I was actually crying due the fact that I would miss yet another assignment deadline, and a couple of days from that I was actually helping my friends with their homework as well. I know how weird it might sound, but really Algebra Helper helped me a lot.
It's true, even I've been using this tool since sometime now and it really helped me in solving problems my queries on daily math trivia and daily math trivia . I also used it to clear my concepts in topics such as subtracting exponents and adding numerators. If you are short on time, then I would highly suggest this software, and well even if you have a lot of time in hand, I still would!
slope, hypotenuse-leg similarity and inequalities were a nightmare for me until I found Algebra Helper , which is really the best math program that I have ever come across. I have used it through many math classes – Algebra 1, Algebra 2 and Algebra 2 | 677.169 | 1 |

Using Mathematical Software in High School Math Class: A Case Study
Hui Xu
Abstract—Mathematical software can be used as valuable
teaching tools in high school math education. The software can
convey complex math concepts through the use of interactive
models and engaging 2D/3D visualizations, making difficult
topics come alive and interesting. Maple is advanced
mathematical software with powerful symbolic deduction,
numerical calculation and graphic display abilities. It is very
suitable for high school math class teaching. In this paper, the
Newton iteration method for solving single variable nonlinear
equation was taken as an example to demonstrate how to
introduce math concepts, derive formulae, teach visually and
explore deeply by using Maple in the high school math class. The
teaching effect was evaluated by comparing the innovative
Maple-aid-teaching method with the traditional multimedia
teaching mode. It is found that the innovative method achieved
better teaching effect. | 677.169 | 1 |
4. Equations (Part 2)
In this lecture you will solve equations involving trigonometric functions (sine, cosine and tangent) and exponential functions and logarithms. You will also learn to solve inequalities and systems of equations. | 677.169 | 1 |
• Determine if an equation or inequality is appropriate for a given situation
• Represent and solve mathematical and real world problems with equations and inequalities
• Interpret the solutions to equations and inequalities
• Represent the solutions to inequalities on a number line
• Analyze the relationship between dependent and independent variables through the use of tables, equations and graphs
Beginning experiences in solving equations will require students to understand the meaning of the equation as well as the question being asked. The use of illustrations, drawings, and balance models to represent and solve equations and inequalities will help students to develop this understanding. Solving equations and inequalities will also require students to develop effective strategies such as fact families, and inverse operations. As effective strategies are developed students will revisit rate and proportional reasoning problems and solve them using strategies developed in solving similar one-step equations.
Students will represent, model and solve equations and inequalities that are based on mathematical and real world problems. Presented with these situations, students must determine if a single value is required as a solution or if the situation allows for multiple solutions will be included. This creates the need for both equations (single solution for the situation) and inequalities (multiple solutions for the situation). When working with inequalities, students will work with situations in which the solution is not limited to the set of positive whole numbers but includes positive rational numbers. As an extension to this concept, certain situations may require a solution between two numbers. Therefore, the exploration with students as to what this would look like both on a number line and symbolically will be explored.
The process of translating between mathematical phrases and symbolic notation is essential in the writing of equations/inequalities for a situation. This is a two-way process and students will be able to write a mathematical phrase for an equation.
The goal is to help students connect the pieces. This is done by having students use multiple representations for mathematical relationships. Students will translate freely among the story, words (mathematical phrases), models, tables, graphs and equations/inequalities. Given any one of these representations students should be able to develop the others
Learning.
KEY STANDARDS
Reason about and solve one-variable equations and inequalities.
MCC6.EE.5
MCC6.EE.6 Use variables to represent numbers and write expressions when solving a
real-world or mathematical problem; understand that a variable can represent an
unknown number, or, depending on the purpose at hand, any number in a specified set.
MCC.6.EE.7 Solve real-world and mathematical problems by writing and solving equations of the form and for cases in which p, q and x are all nonnegative rational numbers. qpx=+qpx=
MCC.6.EE.8 Write an inequality of the form or to represent a constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form or have infinitely many solutions; represent solutions of such inequalities on number line diagrams. cx< cx>cx< cx<
Represent and analyze quantitative relationships between dependent and
independent variables.
MCC6.EE.9
Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one
quantity, thought of as the dependent variable, in terms of the other quantity, thought of as the independent
variable. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation.
Understand ratio concepts and use ratio reasoning to solve problems.
MCC.6.RP.3 Use ratio and rate reasoning to solve real-world and mathematical problems, e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
MCC.6.RP.3a Make tables of equivalent ratios relating quantities with whole-number measurements, find missing values in the tables, and plot the pairs of values on the coordinate plane. Use tables to compare ratios.
The Standards for Mathematical Practice describe varieties of expertise that mathematics educators at all levels should seek to develop in their students. These practices rest on important "processes and proficiencies" with longstanding importance in mathematics education. The first of these are the NCTM process standards of problem solving, reasoning and proof, communication, representation, and connections. The second are the strands of mathematical proficiency specified in the National Research Council's report Adding It Up: adaptive reasoning , strategic competence, conceptual understanding (comprehension of mathematical concepts, operations and relations), procedural fluency (skill in carrying out procedures flexibly, accurately, efficiently and appropriately) and productive disposition (habitual inclination to see mathematics as sensible, useful, and worthwhile, coupled with a belief in diligence and one's own efficacy).
1. Make sense of problems and persevere in solving them. In grade 6, students solve problems involving ratios and rates and discuss how they solved them. Students solve real world problems through the application of algebraic and geometric concepts. Students seek the meaning of a problem and look for efficient ways to represent and solve it. They may check their thinking by asking themselves, "What is the most efficient way to solve the problem?", "Does this make sense?", and "Can I solve the problem in a different way?"
2. Reason abstractly and quantitatively.
In grade 6, students represent a wide variety of
real world contexts through the use of real numbers and variables in mathematical
expressions, equations, and inequalities. Students contextualize to understand the meaning of the number or variable as related to the problem and decontextualize to manipulate symbolic representations by applying properties of operations.
3. Construct viable arguments and critique the reasoning of others. In grade 6, students construct arguments using verbal or written explanations accompanied by expressions, equations, inequalities, models, and graphs, tables, and other data displays (i.e. box plots, dot plots, histograms, etc.). They further refine their mathematical communication skills through mathematical discussions in which they critically evaluate their own thinking and the thinking of other students. They pose questions like "How did you get that?", "Why is that true?" "Does that always work?" They explain their thinking to others and respond to others' thinking.
4. Model with mathematic contextually s. In grade 6, students model problem situations symbolically, graphically, tabularly, and contextually. Students form expressions, equations, or inequalities from real world contexts and connect symbolic and graphical representations. Students begin to explore covariance and represent two quantities simultaneously. Students use number lines to compare numbers and represent inequalities. They use measures of center and variability and data displays (i.e. box plots and histograms) to draw inferences about and make comparisons between data sets. Students need many opportunities to connect and explain the connections between the different representations. They should be able to use all of these representations as appropriate to a problem context.
5. Use appropriate tools strategically. Students consider available tools (including estimation and technology) when solving a mathematical problem and decide when certain tools might be helpful. For instance, students in grade 6 may decide to represent similar data sets using dot plots with the same scale to visually compare the center and variability of the data. Additionally, students might use physical objects or applets to construct nets and calculate the surface area of three dimensional figures.
6. Attend to precision. In grade 6, students continue to refine their mathematical communication skills by using clear and precise language in their discussions with others and in their own reasoning. Students use appropriate terminology when referring to rates, ratios, geometric figures, data displays, and components of expressions, equations or inequalities.
7. Look for and make use of structure. Students routinely seek patterns or structures to model and solve problems. For instance, students recognize patterns that exist in ratio tables recognizing both the additive and multiplicative properties. Students apply properties to generate equivalent expressions
= 12 by subtraction property of equality), c=6 by division property of equality). Students
compose and decompose two and three dimensional figures to solve real world problems involving area and volume.
8. Look for and express regularity in repeated reasoning. In grade 6, students use repeated reasoning to understand algorithms and make generalizations about patterns.
During multiple opportunities to solve and model problems, they may notice that a/b ÷ c/d = ad/bc and construct other examples and models that confirm their generalization. Students connect place value and their prior work with operations to understand algorithms to fluently divide multidigit numbers and perform all operations with multidigit decimals. Students informally begin to make connections between covariance, rates, and representations showing the relationships between quantities.

Addition Property of Equality: Adding the same number to each side of an equation produces an equivalent expression.
• Constant of proportionality: The constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the constant of proportionality. In a proportional relationship, y = kx, k is the constant of proportionality, which is the value of the ratio between y and x.
• Direct Proportion (Direct Variation): The relation between two quantities whose ratio remains constant. When one variable increases the other increases proportionally: When one variable doubles the other doubles, when one variable triples the other triples, and so on. When A changes by some factor, then B changes by the same factor: A=kB, where k is the constant of proportionality.
• Division Property of Equality: States that when both sides of an equation are divided by the same number, the remaining expressions are still equal
• Inverse Operation: A mathematical process that combines two or more numbers such that its product or sum equals the identity.
• Multiplication Property of Equality: States that when both sides of an equation are multiplied by the same number, the remaining expressions are still equal.

I'm getting really bored in my math class. It's polynomial rational exponents, but we're covering higher grade material. The concepts are really complex and that's why I usually doze off in the class. I like the subject and don't want to fail , but I have a big problem understanding it. Can someone help me?
Hey friend ! Learning polynomial rational exponents online can be a disaster if you are not a professional at it. I wasn't an expert either and really regretted my decision until I found Algebrator. This little software has been my buddy since then. I'm easily able to solve the questions now.
I agree , a good software can do miracles . I used a few but Algebrator is the greatest. It doesn't make a difference what class you are in, I myself used it in Intermediate algebra and Intermediate algebra as well , so you don't have to be concerned that it's not on your level. If you never used a program before I can tell you it's not hard , you don't have to know much about the computer to use it. You just have to type in the keywords of the exercise, and then the software solves it step by step, so you get more than just the answer.
I guess you can find all details at this From what I understand Algebrator comes at a cost but it has unconditional money back guarantee. That's how I purchased it. I would advise you to give it a shot. Don't think you will want to get your money back.
system of equations, logarithms and adding matrices were a nightmare for me until I found Algebrator, which is truly the best math program that I have ever come across. I have used it through many math classes – Remedial Algebra, Algebra 2 and Remedial Algebra. Simply typing in the math problem and clicking on Solve, Algebrator generates step-by-step solution to the problem, and my algebra homework would be ready. I highly recommend the program. | 677.169 | 1 |

What is a Study Group?
These week-long workshops were initiated by the University of
Oxford in 1968, and provide a forum for industrial scientists to work
alongside academic mathematicians on problems of direct industrial
relevance. At each Study Group, mathematicians from around the world
gather to work intensively on problems brought by outside companies.
The problems can come from a variety of areas, including: fluid
mechanics, chemistry, electronics, engineering, transport,
environment, finance, optimisation, biology and medicine.
The meeting starts on Monday morning with a series of
presentations from the companies that outline the problem they would
like investigated. The participants then split into groups to work on
the different problems for the rest of the week. On the Friday, each
group delivers an oral presentation to the meeting on the progress
they have made on the problem. A formal written report of the work is
also produced following the meeting. Further collaborations between
the companies and the academics may then result.
The success of the Study Groups' unique format, which uses problems
presented by industry as a basis for mathematical research, is
demonstrated by the extent to which it has been copied around the
world and is now extending into other areas where mathematics may be
applied. More details about the meetings can be obtained from the Mathematics in Industry
Information Service.
Background Information for
Problem Presenters
Once a problem has been agreed, problem presenters will need to
prepare a written problem description to go on this website and in the
booklet issued to participants. The description is usually two or
three sides of A4, but can be longer or shorter if required. On the
first day of the workshop, the problem presenter will give a
presentation on their problem, usually lasting around half-an-hour,
including time for questions from the audience.
A crucial aspect of the Study Groups is the interaction between the
mathematical modellers and the problem presenters. The modellers will
largely be coming at the problems cold, and so are likely to have lots
of questions to ask the presenters as they try to understand what is
important to consider and what is not. It is therefore important that
the problem presenters are in attendance for most of the meeting. In
particular, the presenters must be present for the first day, in order
to present the problem and answer any immediate questions when the
groups first meet.
Each company pays to bring a problem to the meeting. In return the
company will benefit from the work carried out by the participants,
the interaction with academics, and the written report on the problem.
Further collaborations or consultancy can be considered after the
meeting if the company is interested. It is important to note that the
initial work at the Study Group is not subject to any confidentiality
agreement, and that the problem descriptions and reports will be
published on the internet. Any subsequent work following the meeting
can be carried out under any terms agreeable by the parties.
Background Information for
Mathematical Participants
As with previous study groups, there was no registration fee and
board and lodging is provided free of charge for participants. All
participants had to fund was their travel costs to get to the meeting.
Accommodation was provided from Sunday night to Thursday night
inclusive, with meals from Monday Breakfast to Friday lunch
inclusive.
As in previous years,
a Graduate
Modelling Camp was run in Oxford in the week prior to the main
meeting. The camp is intended for PhD students who haven't attended a
study group before, in order for them to get a taste of the modelling
that will go on the following week. Registration for the camp has now
closed, and successful applicants will be notified shortly. Those
attending the camp will be guaranteed a place at the main study
group.
