This is one of these AP free response questions divided into a,b,c,d,etc. but im just going to ask for a small part of the problem.
I need to integrate y=7tecost
The Attempt at a Solution
I tried using U substitution but it didn't work. I tried things like the following:
Integrate with respect to t (dt).
make ecost=u and t=-cosln(t)
but it seems I am complicating my life. Any tips?
