The concept of an integral transform is undoubtedly familiar to the reader in its manifestation as the Laplace transform. This is a useful mechanism for handling certain differential equations. In general, integral transforms are helpful in problems where there is a function f to be determined from an equation that it satisfies. A judiciously chosen transform is then applied to that equation, the result being a simpler equation in the transformed function F. After this simpler equation has been solved for F, the inverse transform is applied to obtain f. We illustrate with the Laplace transform.
