Introduction
The figures below are examples of typical periodic functions with the associated
fourier series. I have also included plots generated using Mathcad illustrating what results from
the series with a small mumber of terms included.
1)

Plotted from 0 to 2π with A = 4,0 and with 5 terms )

2)

Plotted from 0 to 2π with A = 4 , α =2 and with 6 terms )
