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

Differentiation and the Laplace Transform

We will confirm that this is valid reasoning when we discuss the “inverse Laplace transform” in the next chapter. In general, it is fairly easy to find the Laplace transform of the solution to an initial-value problem involving a linear differential equation with constant coefficients and a ‘reasonable’ forcing function1. Simply take ...
