Homeworks
(due in class every Thursday except when
explicitly noted otherwise)
It is understood implicitly that reading the respective
sections from the book (as well as any supplementary materials
that may be provided) and carefully reviewing the lecture notes
is a part of your homework assignment.
Show all work on
your homework solutions - it is not the correct answer you are
graded on, it is the solution and details of the proof. Please
write neatly, and present your solution/proof accurately.
Please check this page regularly
- assignments and due
dates may change depending on the class progress.
