Find the full series of sinx on (-l,l) in its real and complex forms. Assume that l is not an integer multiple of . Hint: First find the series for .

I don't see how finding the fourier series of helps in finding the series for sinx.

The reason they said that is because:

So I simplified the complex version for the coefficient of the fourier series to

I'm not sure how to simplify it from here.

To simplify we can use the fact that to get that

Thus
