NFourierSinCoefficient


gives a numerical approximation to the n^(th) coefficient in the Fourier sine series expansion of expr, where expr is a periodic function of t with period .
  • The numerical approximation to the n^(th) coefficient in the Fourier sine series expansion of expr is by default defined to be NIntegrate[expr Sin[n t], {t, 0, }], where n must be an integer.
  • Different choices for the definition of the Fourier sine series expansion can be specified using the option FourierParameters.
