Differential Equations: Fourier Series and Partial Differential Equations (edX)

In this course, we will use Fourier series methods to solve ODEs and separable partial differential equations (PDEs). You will learn how to describe any periodic function using Fourier series, and will be able to use resonance and to determine the behavior of systems with periodic input signals that can be described in terms of Fourier series. This course will use MATLAB to assist computations.

In this course we will explore:

- How to process noisy sound files

- The way a beam bends in response to external forces

- How to design of ovens to create strong but lightweight composites

- The motion of a violin string

This course is part of the 18.03x Differential Equations XSeries Program.
