Solving laplace transform.

To solve differential equations with the Laplace transform, we must be able to obtain \(f\) from its transform \(F\). There’s a formula for doing this, but we can’t use it because it requires the theory of functions of a complex variable. Fortunately, we can use the table of Laplace transforms to find inverse transforms that we’ll need.

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).
