Box and Whisker Plots
A box and whisker plot for a list of numbers is a picture built on a number line that uses five numbers: the lowest and highest values in the list, and the quartiles Q[1], Q[2], Q[3]. Try not to
shave for two days before attempting one of these plots, since we'll need your whiskers to be nice and ... | 4 | [

Help with integration problem
This problem has been worked out for me, but I am confused about what exactly is going on in it.
Problem: Find the indefinite integral.

Step 1: Let u= 2t -1
Step 2: du= 2 dt

I do not understand problmes 9 to 15 how do you determine domains and ranges again?
Let's look at 9 first: $y=(x+1)^2-3$ A function's domain is all the possible x values that work within a function. A domain is often restricted by functions like $\frac{x}{x-1}\$where $x eq 1$
because that would result in dividing by 0.... | 4 | [

Dual space
Let V be a vector space over field F.Let g,f1,f2,...fk belong to V* i.e;dual of v,then show that g belongs to span{f1,f2,...,fk} if and only if intersection of kernel(fi) i=1 to k is subset of
Kernel(g)..

recursive-functions
In Scheme, you will often end up writing recursive solutions for your problems. To help you do that, there's a simple pattern on how to think up such solutions. This text tries to explain this to
you. You should have some basic understanding of the procedures CONS, CAR and CDR, and the DEFINE form ... | 5 | [
