  2. Assignment:1 • . The problem statement, all variables and given/known dataThe voltage across and current through a certain device are given by:v(t) = 5cos(4*pi*t)i(t) = .1cos(4*pi*t)Determine:(a) the instantaneous power p(t) at t= 0 and t = .25 seconds(b) the average power pav, defined as the average value of p(t) over a full time period of the cosine function (0 to .5 seconds)
