+33661 There are various measures of amplitude: peak amplitude, peak-to-peak amplitude, root-mean-square amplitude etc.
However, perhaps the most common is just peak amplitude, so, when we have y = A*sin(x) we tend to refer to A as the amplitude (or -A if A is negative). In the case of y = sin(x), A is 1, so the amplitude is 1.
