We have:(adsbygoogle = window.adsbygoogle || []).push({});

Period T = 4, so fundamental frequency w0 = pi/2.

This question seems sooo easy. But when I use the integral:

x(t) = Σa[k] * exp(i*k*pi/2*t).

I get 1 + sum(cos(k*pi/2*t)), which does not converge.

Where did I went wrong ?

Thanks a lot for your help.
