Introduction to the Laplace Transform; Basic Formulas Pt 2
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.

Staff Review
This is a continuation of the previous lesson on the Laplace Transform derivation. We finally get the Laplace Transform at the end of this lecture. A must-see for those of you who want to know how to come up with this formula.
