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.
