Chapter 26, Problem 2P

If the Fourier series for the waveform in Fig. 26.33(a) is

$\text{i =}\frac{\text{2Im}}{\text{π}}\text{(1+}\frac{\text{2}}{\text{3}}\text{cos 2wt-}\frac{\text{2}}{\text{15}}\text{cos 4wt+}\frac{\text{2}}{\text{35}}\text{cos 6wt+}\mathrm{...}$ find the Fourier series representation for waveforms (b) through (d).
