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.
Specifying a sine (or cosine) curve with a given amplitude, period, and phase shift defines a unique set of points in the plane. However, there are infinitely many equations that can describe that set of points! For example, the set of points given by the sine curve with amplitude $\,5\,$, period $\,3\,$, and phase shift $\,2\,$.
