3.24. Let x(1) = t, 0 ≤1≤1 2- -1, ISIS 2 be a periodic signal with fundamental period T = 2 and Fourier coefficients ak. (a) Determine the value of ao.

(b) Determine the Fourier series representation of dx(t)/dt. (c) Use the result of part (b) and the differentiation property of the continuous-time Fourier series to help determine the Fourier series coefficients of x(t).
