Amplitude is the height from the mean, or rest, value of the function to its maximum or minimum. The period is the distance required for the function to complete one full cycle. For the sine function, the amplitude is given by and the period is defined as. The same is true for a cosine function.
The amplitude of the graph of y = a cos bx is the amount by which it varies above and below the x-axis. Amplitude = | a |. The period of a cosine function is the length of the shortest interval on the x-axis over which the graph repeats.Period =. Example : Sketch the graphs of y = cos x and y = 2 cos x. Compare the graphs. For the function y = 2 cos x, the graph has an amplitude 2.Since b = 1, the graph has a period of. Thus, it cycles once from 0 to with one maximum of 2, and one minimum of â2. Observe the graphs of y = cos x and y = 2 cos x.he amplitude of the graph of y = a cos bx is the amount by which it varies above and below the x-axis. Amplitude = | a |. The period of a cosine function is the length of the shortest interval on the x-axis over which the graph repeats.
