Consider a case when the constant A=3 and T=8s. Plot the graph of x= 3sin(pi*t/4) and the graph of x=3cos(pi*t/4). Note that the values of t on the horizon axis are given in seconds.

For each plot you should graph a total of 11 points. That is for each second along the horizon axis starting at t = 0s up to and including t =10s. The quantity, x, at each point should be rounded to one decimal place.
