May 26, 2020 · We are going to be given a transform, \(F(s)\), and ask what function (or functions) did we have originally. As you will see this can be a more complicated and lengthy process than taking transforms. In these cases we say that we are finding the Inverse Laplace Transform of \(F(s)\) and use the following notation.

The Inverse Laplace Transform can be described as the transformation into a function of time. In the Laplace inverse formula F (s) is the Transform of F (t) while in Inverse Transform F (t) is the Inverse Laplace Transform of F (s). Therefore, we can write this Inverse Laplace transform formula as follows: f (t) = L⁻¹ {F} (t) =

Theorem 26.2 (linearity of the inverse Laplace transform) The inverse Laplace transform transform is linear. That is, L−1[c 1F 1(s)+c 2F 2(s)+···+c n F n(s)] = c 1L−1[F 1(s)] + c 2L[F 2(s)] + ··· + c nL[F n(s)] when each c k is a constant and each F k is a function having an inverse Laplace transform. Let’s now use the linearity to ...

The inverse Laplace transform is the transformation of a Laplace transform into a function of time. If L{f(t)} = F(s) then f ( t) is the inverse Laplace transform of F ( s ), the inverse being written as: [13]f(t) = L − 1{F(s)} The inverse can generally be obtained by using standard transforms, e.g. those in Table 6.1.
