Differential Equations

Unit III: Fourier Series and Laplace Transform

ODE's with Periodic Input, Resonance

« Previous | Next »

Session Overview

We learn how to solve constant coefficient DE’s with periodic input. The method is to use the solution for a single sinusoidal input, which we developed in Unit 2, and then superposition and the Fourier series for the input. We also discuss the relationship of Fourier series to sound waves.
