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 cosine of a real number t is the x-coordinate of the point P in the following diagram, where | t | is the length of the arc shown. cos t = x-coordinate of the point P sin t = y-coordinate of the point P Graph of the Cosine Function. y = cos x. General Cosine Function. The generalized sine function has the following form: y = A cos[Ï(x - Î±)] + C. 1  A is the amplitude (the height of each peak above the baseline). 2  C is the vertical offset (height of the baseline). 3  P is the period or wavelength (the length of each cycle).
