We use t as the independent variable for f because in applications the Laplace transform is usually applied to functions of time. The Laplace transform can be viewed as an operator L that transforms the function f = f(t) into the function F = F(s). Thus, Equation 7.1.2 can be expressed as. F = L(f).To understand the Laplace transform formula: First Let f (t) be the function of t, time for all t ≥ 0 Then the Laplace transform of f (t), F (s) can be defined as Provided that the integral exists.

We also illustrate its use in solving a differential equation in which the forcing function (i.e. the term without an y’s in it) is not known.This is a linear homogeneous ode and can be solved using standard methods. Let Y (s)=L [y (t)] (s). Instead of solving directly for y (t), we derive a new equation for Y (s). Once we find Y (s), we inverse transform to determine y (t). The first step is to take the Laplace transform of both sides of the original differential equation.The inverse Laplace transform is a linear operation. Is there always an inverse Laplace transform? A necessary condition for the existence of the inverse Laplace transform is that the function must be absolutely integrable, which means the integral of the absolute value of the function over the whole real axis must converge.step 4: Check if you can apply inverse of Laplace transform (you could use partial fractions for each entry of your matrix, generally this is the most common problem when applying this method). step 5: Apply inverse of Laplace transform.$\begingroup$ In general, the Laplace transform of a product is (a kind of) convolution of the transform of the individual factors.
