Using MatLab, plot the signal x(t) = 10*cos(800*pi*t + pi/4). Use 5 samples per period and plot 3 periods using equations for each variable that are derived from the frequency, f, instead of hard-coding numbers where possible. Explain and/or annotate each of the parameters from x(t) = A*cos(w*t + phi) in the code.
