Brief Introduction
In order to understand most phenomena in the world, we need to understand not just single equations, but systems of differential equations. In this course, we start with 2x2 systems.
Description
Differential equations are the language of the models we use to describe the world around us. Most phenomena require not a single differential equation, but a system of coupled differential equations. In this course, we will develop the mathematical toolset needed to understand 2x2 systems of first order linear and nonlinear differential equations. We will use 2x2 systems and matrices to model:
- predator-prey populations in an ecosystem,
- competition for tourism between two states,
- the temperature profile of a soft boiling egg,
- automobile suspensions for a smooth ride,
- pendulums, and
- RLC circuits that tune to specific frequencies.
The five modules in this seriesare being offered as an XSeries on edX. Please visit the Differential EquationsXSeries Program Page to learn more and to enroll in the modules.
