Homework for Differential Equations

The title of the page says it all.

Well, almost.

Note that while it is fine to talk to others in the class (fellow students, TAs, instructor, etc.) about the homework problems what you submit needs to be your understanding of the mathematics, and only your understanding of the mathematics. Make sure to cite any additional texts or tools used, or anyone with whom you collaborated. You will not receive full credit unless you provide full justification. Also, please make sure that your work (when applicable) is stapled, and that the front page includes your full name and your recitation section.

Last, if you have any questions about this material or feel that there is a typo, etc., please email me or stop by office hours as soon as possible.
