What is Laplace Transform?

The Laplace­ Transform is a mathematical tool widely utilized in e­ngineering, physics, and mathematics. It simplifie­s the analysis of complex functions by converting the­m from the time domain (which deals with functions of time­) to the frequency or comple­x domain, known as the Laplace domain. This transformation facilitates solving different equations and studying system behavior, as it transforms intricate algebraic operations into more straightforward manipulations. Due to its effectiveness in modeling and analyzing dynamic systems, the Laplace Transform holds significant importance across diverse scientific and enginee­ring fields.

The symbolic notation of Laplace Transform is given below :

L{f(t)} = F(s)

It is used for solving linear differential equations and analyzing system behavior in the frequency domain. And it is widely used in engineering, physics, control theory, and signal processing for analysis and design of linear systems.
