Since an integral is not affected by the changing of its integrand at a few isolated points, more than one function can have the same Laplace transform. Example 6.24 illustrates that inverse Laplace transforms are not unique. However, it can be shown that, if several functions have the same Laplace transform, then at most one of them is ...

Laplace Transform The Laplace transform is a method of solving ODEs and initial value problems. The crucial idea is that operations of calculus on functions are replaced by operations of algebra on transforms . Roughly, differentiation of f(t) will correspond to multiplication of L(f) by s (see Theorems 1 and 2) and integration of
