H.W. 1. Determine the exponential form of the Fourier series for the periodic function defined by: f(x)= -2, when -sxs- 2, when sxs+ and has a period of 2x. π -2, when + SXS+ 2. Show that the exponential form of the Fourier series in Problem 1 is equivalent to: 8 f(x)-(cosx-cos 38+0065x-0067x+) = 元 cos
