# Fourier Series of Sin^2(x)

Discussion in 'Homework Help' started by Fahrad, Oct 28, 2013.

Hello. We were asked to perform the Fourier Series of Sin$^{2}$(x). I just want to ask if I did it the right way.
I stopped right after I got the A$_{k}$ since I'm not sure if I'm doing it correctly. Also, I plotted the above equation in MATLAB and found out that it is an even function so I suppose B$_{k}$ = 0.
