Understanding the Laplace Transform

In this video, Alex introduces the concept of the Laplace Transform, explaining its definition and the conditions under which it applies. The video details the formula for the Laplace Transform, which involves integrating a function f(t) multiplied by e^(-st) from 0 to infinity. Alex demonstrates how to substitute the function into the formula and perform the integration to obtain the transformed function F(s). The video concludes with an explanation of the Laplace Transform operator, which converts the function f(t) into F(s).
