Hi,
I'm trying to solve the following integral:
I'm under the impression it can be solved as an elliptical integral, but I'm unsure how I would get it into such a form. I've tried applying the sum-difference formula to the cosines, but I didn't find that helpful either. Any help that can be offered is appreciated; I need to understand the steps involved in solving it, so simply pushing it into Wolfram and getting an answer is not going to help me. Thanks in advance.
