NFourierCosTransform

NFourierCosTransform[expr, t, ]
gives a numerical approximation to the Fourier cosine transform of expr evaluated at the numerical value , where expr is a function of n.
  • The numerical approximation to the Fourier cosine transform of expr is by default defined to be .
  • Different choices for the definition of the Fourier cosine transform can be specified using the option FourierParameters.
  • With the setting FourierParameters->{a, b}, the Fourier cosine transform computed by NFourierCosTransform is .
