An undergraduate course on differential equations aimed at engineers and other STEM fields.

In this lecture, we look at autonomous equations, classifying their critical points, and figuring out the long term behavior of the solutions.

The book for this course is at https://www.jirka.org/diffyqs/

The book is free to download as PDF, or browsable as webpages, or you can buy an inexpensive paperback version (best way to support this project).
