Unless you are solving a partial differential equation, such that the Laplace transform produces an ordinary differential equation in one of the two variables and a Laplace transform of ‘t’, dsolv e is not appropriate.

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).Laplace Transform: Existence Recall: Given a function f(t) de ned for t>0. Its Laplace transform is the function de ned by: F(s) = Lffg(s) = Z 1 0 e stf(t)dt: Issue: The Laplace transform is an improper integral.

FollowSolving ODEs with the Laplace transform Laplace transforms of derivatives. One of the most important properties of the Laplace transform is how it affects derivatives of functions. If f(t) is differentiable function, then we can write the Laplace transform of f in terms of the transform of f using integration by parts:We repeat the previous example, but use a brute force technique.
