Consider the Fourier Series for the periodic function given.
x(t) = 5 - 10cos(10^6)t + 4cos(10^7)t + sin(1.1*(10^7)t)
a.) find the fourier coefficients of the exponential form
b.) find the fourier coefficients of the combined trigonometric form
c.) plot both the single sided and double sided amplitude and phase spectra
