| Title | Summary |
|---|---|
| Definitions and Basic Concepts | Paul's On-Line Notes introducing differential equations. They give basic definitions of ordinary and partial differential equations, order, linear and nonlinear differential equations, solutions, initial-value problems, and intervals of validity (intervals of definition). |
| Final Thoughts on Basic Concepts | Paul's On-Line Notes on general questions about the solutions of
differential equations that will be addressed in his course. They align well with the general questions addressed in our course. |
