# Math Help - Fourier coefficients

1. ## Fourier coefficients

I have some difficulties with solving this. Could you please help me out? I got not real solutions:S

You can see the picture attached.

The cut signal is the bolt, blue curve.
Find Fourier coefficients to the cut signal when L=0.5.

Split the defining integrals for the coefficients into five pieces $0$ to $\pi/6$, $\pi/6$ to $5\pi/6$, $5\pi/6$ to $7\pi/6$, $7\pi/6$ to $11\pi/6$.
