Also, calculate the power using at least 2 methods: directly from x(t), and using Parsevals relation.

(a) Determine if the waveform has de, even, or odd symmetry. (b) Obtain its cosine/sine Fourier series representation. (c) Convert the representation to amplitude/phase format and plot the line spectra for the first five non-zero terms. (d) Convert the representation to complex exponential format and plot the line spectra for the first five non-zero terms. (e) Use MATLAB or MathScript to plot the waveform using a truncated Fourier series representation with max = 100. 5.8 Waveform in Fig. P5.8 with A = 6. 101 t(s) -3 -2 -1 0 1 2 3 Figure P5.8: Waveform for Problem 5.8.
