Lesson Summary:

In this lesson, we are introduced to the Laplace Transform and learn some basic formulas for its use. The Laplace Transform is the continuous analog of summation of a power series. By replacing N with a continuous variable T and using integration instead of summation, we can turn a function defined for positive values of T into a function of S. The goal is to make the integral converge, so we need X to be a positive number less than 1. By changing the variables and naming conventions, we end up with a function F of S, which is no longer a function of X. This is called a little plus transform.
