Unformatted text preview: angle goes from 0 to 2 . Here, we are taking the sine of the angle x . So as x goes from 0 to 2 , an entire cycle of the function y = A sin ( x ) will be traced out. That cycle starts when x = x = and ends when x = 2 x = 2 + . Thus, the graph of y = A sin ( x ) is just the graph of y = A sin x shifted horizontally by , as in Figure 5.2.11. The graph is shifted to the right when > 0, and to the left when < 0. The amount of the shift is called the phase shift of the graph. x y A A 2 + period = 2 phase shift (a) > 0: right shift x y A A 2 + period = 2 phase shift (b) < 0: left shift Figure 5.2.11 Phase shift for y = A sin ( x )...
