Here's the most intuitive introduction to Differential Equation that I have ever seen: https://www.complexityexplorer.org/courses/31-introduction-to-differential-equations https://www.complexityexplorer.org/courses/31-introduction-t... Explains DEs from scratch, physical significance, one or two traditional methods, then goes on to numerical methods. If you ever want to learn DEs, I HIGHLY recommend this tutorial. This is short, too. I have never found a resource where the concepts behind DEs are explained better. This tutorial won't prepare you for a course, or tell you everything there is to know about DEs, of course.
