Formal definition The Laplace transform of a function f(t), defined for all real numbers t ≥ 0, is the function F(s), which is a unilateral transform defined by (Eq.1) where s is a complex frequency domain parameter with real numbers σ and ω . An alternate notation for the Laplace transform is instead of F. [3]Sympy provides a function called laplace_transform which does this more efficiently. By default it will return conditions of convergence as well (recall this is an improper integral, with an infinite bound, so it will not always converge). If we want just the function, we can specify noconds=True. 20.3.

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).
