EE310-Lecture 21-Laplace Transform-Introduction and Properties

Introduction and Properties of Laplace Transforms. Lecture covers Sections 15.1 to 15.3 of Alexander and Sadiku’s “Electric Circuits.” Professor Dorr’s lectures on Laplace Transforms use his “Laplace Transform Roadmap” graphic which can be used to intuitively show the flow for all problems in Chapter 15 – you can always see how your steps fit into the big picture. Examples of taking Laplace Transforms using integration, tables, and properties.

Not that big of a a deal but there is a mistake at 1:05:05. The derivative of (S+1)/(S^2 + 2S +2 ) = -S(S+2)/(S^2 + 2S +2)^2. Then afterwards we multiply that derivative by negative 1. So the final answer should be positive not negative.
