1. The problem statement, all variables and given/known data 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 3. 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?
