## Plot a Sinusoid

### Description

Plots a sinusoid over 0 to 2π.

### Usage

sinusoid(amplitude, frequency, phase, ...)


### Arguments

 amplitude the amplitude of the sinsuoid (its maximum value). frequency the frequency of the sinusoid in 0 to 2π (number of cycles). phase the phase of the sinusoid (location of the peak). ... additional arguments passed to the plot.

### Details

Sinusoidal curves are useful for modelling seasonal data. A sinusoid is plotted using the equation: A\cos(ft-P), t=0,…,2 π, where A is the amplitude, f is the frequency, t is time and P is the phase.
