NFourierCosCoefficient

NFourierCosCoefficient[expr, t, n]
gives a numerical approximation to the n

coefficient in the Fourier cosine series expansion of expr, where expr is a periodic function of t with period 1.

To use NFourierCosCoefficient, you first need to load the Fourier Series Package using Needs["FourierSeries`"].

The numerical approximation to the n coefficient in the Fourier cosine series expansion of expr is by default defined to be for n>0 and for n0.

Different choices for the definition of the Fourier cosine series expansion can be specified using the option FourierParameters.

With the setting FourierParameters->{a, b}, expr is assumed to have a period of , and the n coefficient computed by NFourierCosCoefficient is for n>0 and for n0.

In addition to the option FourierParameters, NFourierCosCoefficient can also accept the options available to NIntegrate. These options are passed directly to NIntegrate.
