How to graph sinusoids

First you must determine all the necessary information to begin graphing a sinusoid.
The elements you will need to graph these are:
Amplitude - the distance from the center points to the minimum or maximum values.
Period - The amount of time it takes to complete one cycle.
Key Point Interval - The intervals you will go by on the axis of your graph.
Frequncy - The amount of cycles that pass in one second
Parent Functions
y=sinx                                                          y=cosx
Period: 2π                                                                       Period: 2π
Key Pt. Int.: 2π/4 = π/2                                               Key Pt. Int.: 2π/4 = π/2

                                              Frequency=b/2π
