How do you graph any sinusoidal graph?
Suppose the graph is of the form y = A sin (bx + c) + d
Then the amplitude is A and represents the maximum value of the range on the y axis. The period can be given by 2pi/b and represents the number of radians on the x axis for a complete cycle of the curve. The c value represents the phase angle shift and indicates how many radians the graph is shifted left or right from the origin. The d represents a vertical transformation and indicates how many units the graph range is shifted away from the amplitude at the origin.
