This document discusses the Laplace transformation, which converts a function into another function through mathematical manipulation. Specifically, it transforms a differential equation into an algebraic expression that can be easily solved. The document outlines the key topics that will be covered, including the definition of the Laplace transform, using tables of transforms to solve problems, inverse transforms, step functions, and using Laplace transforms to solve initial value problems, especially those involving step functions. It aims to illustrate how Laplace transforms simplify solving differential equations.
