the amplitude of the sinsuoid (its maximum value).
frequency
the frequency of the sinusoid in 0 to 2\(\pi\) (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: \(A\cos(ft-P), t=0,\ldots,2 \pi\), where \(A\) is the amplitude, \(f\) is the frequency, \(t\) is time and \(P\) is the phase.
