FourierCosTransform

FourierCosTransform[expr, t, ω] gives the symbolic Fourier cosine transform of expr.

• FourierCosTransform[expr, {t1, t2, ...}, {ω1, ω2, ...}] gives the multidimensional Fourier cosine transform of expr.

Examples

Compute the Fourier cosine transform:

FourierCosTransform[Exp[-t^2], t, ω]

Transform a Gaussian function:

FourierCosTransform[Exp[-a t] UnitStep[t], t, ω, Assumptions -> a > 0]
