A sample of such pairs is given in Table 5.2.1. Combining some of these simple Laplace transforms with the properties of the Laplace transform, as shown in Table 5.2.2, we can deal with many applications of the Laplace transform. We will first prove a few of the given Laplace transforms and show how they can be used to obtain new transform pairs. The Laplace transform of a function f(t) is defined as F(s) = L[f](s) = ∫∞ 0f(t)e − stdt, s > 0. This is an improper integral and one needs lim t → ∞f(t)e − st = 0 to guarantee convergence. Laplace transforms also have proven useful in engineering for solving circuit problems and doing systems analysis.

There is an axiom known as the axiom of substitution which says the following: if x and y are objects such that x = y, then we have ƒ(x) = ƒ(y) for every function ƒ. Hence, when we apply the Laplace transform to the left-hand side, which is equal to the right-hand side, we still have equality when we also apply the ...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 8.1.3 can be expressed as. F = L(f).Minus f prime of 0. And we get the Laplace transform of the second derivative is equal to s squared times the Laplace transform of our function, f of t, minus s times f of 0, minus f prime of 0. And I think you're starting to see a pattern here. This is the Laplace transform of f prime prime of t.
