Differential Equations Math 244, Fall 2017
The book we're using in the Fall will be "Differential Equations", by Paul
Blanchard, Bob Devaney and Glen Hall (Fourth Edition).
Important NOTE: The book is often sold "with DE Tools
Printed Access Card". We don't require that, so if you're buying
a used version without it, don't worry. Here's an Amazon link
with more book details:

There also is an
optional Student Solution Manual Available
(typically, these have more
detailed solutions to odd numbered problems)
We'll generally be covering topics from Chapters 1-6, as well as Appendices A and B.
