== Part A == hmm...... This signal was not posted in the HW1 rhea, but most people just did cost so i thought i'd do something a little different.
Given the CT periodic signal x(t) = 2sin(t) - cos(t) because it repeats every $ 2\pi $
The signal is not periodic though when in DT (x[t] = 2sin(t) - cos(t)) --> there is no integer N which makes x[n] = x[n + N] true
