Best ResponseYou've already chosen the best response.0The graph of y = cos(x + pi/2) looks a lot like y = cos x. You could see this as follows: cos 0 = 1 is the starting point of the "normal" cos. To get 1 as a result from your function, you need to substitute pi/2 for x. That means the starting point of cos(x + pi/2) has shifted...
