1. The problem statement, all variables and given/known data Fx= sin2x for -pi<x<0 and 0 for 0<x<pi. Compute the coefficients of the Fourier series. 2. Relevant equations 3. The attempt at a solution I found Ao=0 even though I came up with a Fourier cosine series. There must be something wrong. And is that possible that I come up with a fourier cosine series which converges to sin2x?? Before I began doing the problem, I thought An will be equal to zero and Bn will be zero for n≠2 which is intuitively correct. So, anyone has any idea?
