fourier
insympy.series
SeqFormula
class, that knows how to generate coefficients based ona formula
FourierSeries
Class,This Class represents a fourier series expansion.
Contains methods for getting the general representation of series
and for getting the first n terms.
fourier_series
function.It is a wrapper that returns the first n terms of a series or an
infinite generator of terms
I have placed everything in a single file. I think it can be structured better.
May close #9077
