1. The problem statement, all variables and given/known data Integrate from e^x to e^2x: (sin^2(t) + cos^2(t) -1)dt 2. Relevant equations just standard integral equations 3. The attempt at a solution I know how to do most of it, my only question is: is (sin^2(e^2x) + cos^2(e^x) -1) a special trig identity? or would i just solve it like a normal interation in parts problem?
