Integrals involving trigonometry In this section we are going to look at quite a few integrals involving trig functions and some of the techniques we can use to help us evaluate them. Let’s start off with an integral that we should already be able to do. This integral is easy to do with a substitution because the presence of the cosine, however, what about the following integral. Example 1 Evaluate the following integral. Solution This integral no longer has the cosine in it that would allow us to use the substitution that we used
