1. The problem statement, all variables and given/known data So I know how to evaluate the integral from 0 to 2pi of 1/2+cos theta. However, the question I am being asked to do has me calculate this integral from 0 to pi. I am not sure what adjustment is necessary to get the integral i am given (from 0 to pi) to the form I know how to calculate (0 to 2pi). 2. Relevant equations Given integral 3. The attempt at a solution at first I thought that since cosine is an even function I could merely double the integral's bounds and divide it by two since the integral would just pick up an extra half of a periodic function. but the constant and the fact that cosine is in the denominator made me question that idea. so as of right now i am a bit stuck.
