Math 285, Spring 2009
Daily reading and (non-graded) homework guide
Reload this page every time you visit.
This is not a complete list. It will be updated during the semester. Please check it often. But it is always best to come to class regularly.
All of the reading and homework refer to the textbook Differential Equations and boundary value problems, 4th Ed., 2008, by Edwards and Penney.
Remember, these non graded homework do not count toward your grade. You can ask about a particular problem in class and we can discuss it.
