Homework Help: Fourier Series Representation Problem

    1. The problem statement, all variables and given/known data

    Since I don't know how to insert equations into a message here, I've scanned both the problem and my attempt at a solution. Where I run into problems is how to find an. I'm not completely sure how to treat that integral and was hoping somebody could nudge me in the proper direction.

    You messed up writing down the second integral when you integrated by parts, specifically, you dropped the n in the argument. Otherwise, you look like you're on the right track.
