Periodic CT Signal
$ x(t) = cos(3*pi*t + pi) $ $ x(t) = cos(3 pi t+ pi) \! $
Rewritten in $ e^{jw_0} $ Form
$ x(t) = \frac{4\pi}{3} + \frac{1}{j2000}(e^{j1000\pi t}+e^{j-1000\pi t}) - \frac{1}{j1000}(e^{j1000\pi t}-e^{j-1000\pi t}) $
Fourier Series Coefficients
$ a_0 = \frac{4\pi}{3} $
$ a_1 = \frac{1}{1000} $
$ w_0 = 1000\pi\ $
