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
