About the Textbook
The official course textbook is Zill-Wright 8th Edition. Previous editions will likely do
(come see me if you have doubts about it). I will not be quoting the textbook verbatim other than for the practice questions, so in principle you can do
without any textbook whatsoever; but I strongly suggest you get some differential equations book that covers
the topics in the class.
Suggested practice questions will be taken from the official textbook.
