This page is for recitation sections 1, 2, and 3 of Math 244 (Differential Equations).
Homework and Quizzes
You are strongly encouraged to do the
suggested
homework problems listed on the course webpage.
The book recommends using a computer for some of the problems. You can do
these with Maple (or any other software you like), but it is also useful to
do as much as you can by hand. In particular, you should work on these
whether or not you use Maple.
In addition, there will frequently be homework due in recitation. The
assignment will be posted here and announced in recitation the week
before. Late homework will not be accepted.
Occasionally, instead of collecting homework, I will give a quiz. The
quiz will be based largely on the homework.
