1. The problem statement, all variables and given/known data Evaluate the integral with respect to f of the following function http://img233.imageshack.us/img233/5303/picture1ub7.png [Broken] 3. The attempt at a solution This if for one of my homeworks. I haven't taken a single math course in almost 2 years so I'm kind of rusty. I'm not sure how to evaluate this. I tried moving the 'a' outside the integral but that doesn't help. I believe there is a trig identity I'm supposed to be able to use. Any tips or hints are greatly appreciated.
