Graphing Sine and Cosine

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

    Amplitude =

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
