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.
