Most Difficult Problem on First Test

The problem that I found most difficult was problem number 4.

4. Compute the coefficients $ a_{k} !\ $ of the Fourier series signal $ x(t) !\ $ periodic with period $ T = 4 !\ $ defined by

$ x(t)= \left\{ \begin{array}{ll}0&, -2<t<-1\\ 1&, -1\leq t\leq 1\\ 0&, 1<t\leq 2\end{array}\right. $
