Homework Help: Fourier Sine Series

  1. Jul 24, 2013 #1
    Everything is in the picture I've attached. I believe my work is right because it's not that difficult of a problem but what I'm having a hard time seeing is how i go from the coefficient bn that I've calculated to the final solution. Maybe I did screw up or maybe there's an identity I'm not seeing.

    Anyways if anyone is able to help that would be greatly appreciated thanks! :D

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

    2. Relevant equations

    3. The attempt at a solution

    What does ##b_n## simplify to if ##n## is odd?

    Hey Jbuns Thanks so much I see how odd n's simplify to 0 and how the the terms simplify when n is even. Also thank you for your post on my other question. If you ever need anything! hit me up lol :D
