Finding the Inverse Laplace Transform using Partial Fractions Method

Finding the Inverse Laplace Transform using Partial Fractions Method

It possible touse partial fractions method to find the inverse Laplace transform if Laplace transform F(s)has the

form: F(s)=(N(s))/(D(s)) and the degree of the numerator N(s) is less than the degree of thedenominator D(s).


The first step is to factor the denominator as much as possible. Then for each term in the denominator, we will use




the following table to get terms for partial fraction decomposition, and then find the inverse Laplace transform with

respect of the obtained values.
