Review from Calc 1
You should know the basics from Calc 1 very well: derivatives of basic functions, product rule,
quotient rule, chain rule. From reference page 5 in the back of the book, know #1-9, 11, 13-15
without looking; be familiar with 10, 12, 16-
So far, we have only done integrals of simple functions.
For integration, there is NO product rule, NO quotient rule, NO chain rule.

odd powers of sine and cosine:
We did integrals like this in the previous section using a reduction formula, but lets try a more
generally applicable method. We cant use u = sin x, du = cos x dx, because we
To prepare for section 5.10, we are going back to revisit some types of limits that we couldnt
evaluate before (in calc. 1.) First lets look at some familiar limit situations:
If a function is continuous at x = a, then lim f(x) f(a) . If a fun
Integration using tables:
Find a formula on the table (reference pages 6-10 in the back of the book) that matches or is
similar in form to a given integral. Use substitution or rewrite algebraically to make an exact
match. Use the formula to g
Although the same study methods dont work for everyone, if you find that what you are doing
now is not as effective as you would like, here are some suggestions of things to try.
If you can, look over the class notes or the section in the book before we c
The definition we have used of a definite integral f(x)dx required a finite interval [a, b] of
x-values and an integrand, f(x), that has no infinite discontinuities on [a, b].

Mathematically a sequence is defined as a function whose domain is the set of positive
