Understanding Fourier Coefficients using PDE

[QUOTE="RJLiberator, post: 5354733, member: 504241"] Since f(x) = x is odd, we can safely say a_n is equal to 0 for n >= 0. So, it seems I am right that b_n is the only coefficients. The Fourier expansion is thus 2sin(x)- sin(2x) + (2/3)sin(3x)/3 +...So I guess my understanding on this problem seems to be getting better. My question is thus, according to the question in the initial post, is a complete and safe way to answer this question by stating that the function is odd so a_n coefficients are 0, and so we observe b_n = (2/n)(-1)^(n+1) I just want to make sure I am answering this question with completeness.
