Here are my online notes for my differential equations course that I teach here at Lamar University. Despite the fact that these are my “class notes” they should be accessible to anyone wanting to learn how to solve differential equations or needing a refresher on differential equations. I’ve tried to make these notes as self contained as possible and so all the information needed to read through them is either from a Calculus or Algebra class or contained in other sections of the notes. | Differential Equations This document was written and copyrighted by Paul Dawkins.

Preface Here are my online notes for my differential equations course that I teach here at Lamar University. Despite the fact that these are my class notes they should be accessible to anyone wanting to learn how to solve differential equations or needing a refresher on differential equations. I ve tried to make these notes as self contained as possible and so all the information needed to read through them is either from a Calculus or Algebra class or contained in other sections of the notes. A couple of warnings to my students who may be here to get a copy of what happened on a day that you missed. 1. Because I wanted to make this a fairly complete set of notes for anyone wanting to learn differential equations I have included some material that I do not usually have time to cover in class and because this changes from semester to semester it is not noted here. You will need to find one of your fellow class mates to see if there is something in these notes that wasn t covered in class. 2. Because I want these notes to provide some more examples for you to read through I don t always work the same problems in class as those given in the notes. Likewise even if I do work some of the problems in here I may work fewer problems in class than are presented here. 3. Sometimes questions in class will lead down paths that are not covered here. I try to anticipate as many of the questions as possible in writing these up but the reality is that I can t anticipate all the questions. Sometimes a very good question gets asked
