1. The problem statement, all variables and given/known data Find the exact total of the areas bounded by the following functions: f(x) = sinx g(x) = cosx x = 0 x = 2pi 2. Relevant equations the integral of (top equation - bottom equation) 3. The attempt at a solution Change the window on the graphing calculator to an x scale of 2pi? I'm having trouble finding where x = 2pi. the integral of (cosx - sinx) to me, cosine appears to be the top equation Take the anti-derivative of them both---> (-sinx - cosx) (if i remember correctly) Finding the bounds for the integral is what I'm having problems with. Any hints or suggestions would help me out. This is the last stretch of my ap calculus class, and I guess my brain is starting to fizz out! Thank you everyone!
