If it's finding the integral, first make the substitution . Now make either (not both!!) of the following substitutions 1. (this is the one I prefer). 2. (more work will be required).
Yeah I got up to the substituting part and got confused. I haven't used the first substitution before so I don't know what to do there. I tried using tan and got lost.
After making the subs, did you get it down to: Now, can you do that?. This looks similar to a Fourier series.
