Differential Equations

This course reader accompanies my differential equations course using Zill, Differential Equations with Boundary-Value Problems, 7th ed. It currently covers chapters 1-9 and 12. I skip the last section of Ch. 6 and the last sections of Ch. 9. I also currently only cover chapters 12.1 and 12.2. I plan to cover all sections at some point and replace all of the figures with original work.
