InverseFourierCosTransform

, t]
gives the symbolic inverse Fourier cosine transform of expr.

₁,

₂, ...}, {t₁, t₂, ...}]
gives the multidimensional inverse Fourier cosine transform of expr.

Different choices of definitions can be specified using the option FourierParameters.

With the setting FourierParameters->{a, b} the inverse Fourier transform computed by InverseFourierCosTransform is .

Elementary functions:

Special functions:

Generalized functions:

Multivariate transforms:

Use assumptions to indicate the region of interest for the parameters:

The default setting for FourierParameters is

Use a non-default setting for a different definition of transform:

Use GenerateConditions->True to get parameter conditions for when a result is valid:

For even functions results are identical to InverseFourierTransform:

Inverse Fourier cosine transforms may require generalized functions such as DiracDelta:
