Math 246 Homework and Syllabus, Fall 2009
(22 November version)
Below are the weekly homework assignments. These will not be
collected. However the material from the homework will appear on
the quizzes and exams. The dates given are when the material is
first scheduled to be tested on either an exam or a quiz. Quiz
material should be covered during the lectures and discussion
sections just before the quiz. You are responsible for the
material even if the University closes on the day of the
discussion section. It is a good idea to look over all material
before it is covered in the lectures.
These assignments are subject to changes announced either in class or
on this webpage.
