How do laplace transforms work
WebJul 9, 2024 · 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.
