Consider the following signal:

x(t) = {3\over 4} - \frac{1}{2}\cos(2\pi t) + \frac{1}{2}\sin(6\pi t)

What is the fundamental period of this signal, in seconds?
T_0 =~

In the complex exponential form of the Fourier series, how many of the coefficients X[k] are non-zero?Enter a single number below:

Find the values of the nonzero coefficients X[k] and enter them below. Enter your answers as a Python dictionary mapping k values to X[k] values. Note that you can refer to the imaginary unit as 1j in Python.
