Sine function:

Cosine function:

The amplitude of and represents half the distance between the maximum and minimum values of the function and is given by

a = vertical stretch/shrink amplitude

b = horizontal stretch/shrink period

c = move left or right phase shift

d = move up or down

Period of Sine and Cosine function:

Other info:

X-scale =

Phase shift =

If a is negative, there is an x-axis reflection
