Hi. I want to find the fourier series of

sin^2 x + sin ^3x

and sin θ = [e^iθ - e-iθ]/2i

2. Relevant equations

3. The attempt at a solution

So if i use sin x = [e^ix - e-ix]/2i I will get for the first term:

[e^2ix + e^-2ix -2]/-4

I can do the same for the second term but what do i do from here..? I'm not sure how to integrate these.
