Graphs with equations of the form: y = sin(t) or y = cos(t) are generally called vibration graphs. On these graphs the time needed along the x-axis for one oscillation or vibration is called the period. Graphs with equations of the form: y = sin(x) or y = cos(x) are generally called waveform graphs.
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 |.
