The graph of #1/3cos(x)# looks like this:
graph{1/3cosx [-10, 10, -5, 5]}

Since it is a cosine function, it starts at its highest point, goes to zero, down to lowest point, back up to zero, then back up to highest point in a period of #2pi#
The Amplitude is #1/3# meaning the highest point is #1/3# above the midline, and the lowest point is #1/3# below the midline. The midline for this equation is #y=0#
