(3 pts.) Problem 4 :Graph the following time varying quantities v(t) i(t) the product v(t) i(t) where v(t) = 2 2 sin( t) i(t) = 1 2 sin( t + π ) Assume a frequency of 60 Hz. The time axis for the graphs should be from 0 to 2T (where T is the period of the waveforms) All waveforms should be on the same graph ; identify each waveform, label axis and scale. Any plotting software can be used, Matlab, MathCad, even Excel (or other spread sheet software). (3 pts.)...
