The Inverse Laplace Transform

The fact that the inverse Laplace transform is linear follows immediately from the linearity of the Laplace transform. To see that, let us consider L−1[αF(s)+βG(s)] where α and β are any two constants and F and G are any two functions for which inverse Laplace transforms exist.

The Laplace transform is an operation that transforms a function of t (i.e., a function of time domain), defined on [0, ∞), to a function of s (i.e., of frequency domain)*. F(s) is the Laplace transform, or simply transform, of f (t). Together the two functions f (t) and F(s) are called a Laplace transform pair.

Laplace Transform The Laplace transform can be used to solve di erential equations. Be-sides being a di erent and e cient alternative to variation of parame-ters and undetermined coe cients, the Laplace method is particularly advantageous for input terms that are piecewise-de ned, periodic or im-pulsive.
