Document Summary

Lecture 12 february 3rd, 2022 - using identities . We are studying methods to help us find antiderivatives. So far we have looked at substitution and integration by parts. Another general technique is to use identities to try and make an antiderivative problem simpler, hopefully simple enough so that we can solve it. As an illustration of these kinds of arguments, today we will see how to solve many problems of type. , and problems of the type sin ( )cox ( ) d and dx dx a b. 1 p(x)) where p(x) is a quadratic polynomial. The last two examples from lecture 11 are also examples where an identity is used in the middle of the calculation in order to simplify the problem. 2 sin ( ) + cos ( ) = 1. We will use the identity identity!) as well as the identities: cos ( ) = sin ( ) =
