    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.

    Below is my solution. Sorry for my bad handwriting.
