How to do a laplace transform.

By definition, the Laplace transform L(xa) of the function x ↦ xa is given by L(xa)(s) = ∫∞ 0exp( − sx)xadx. The Gamma function is defind by a similar integral, namely Γ(s) = ∫∞ 0exp( − x)xs − 1dx. The Laplace transform of xa can thus be computed by the variable transformation x ↦ x / s. Share. Cite.
