Homework Assignments for
Dr. Sadun's M340L Sections, Spring 2003
Last updated May 1

There will be homework assigned every week, due on Wednesdays at the beginning of class, every week except those weeks with exams.  Problem numbers (and section numbers) refer to the THIRD edition of Lay's book.

The grader has requested that you please STAPLE your homeworks and fold them lengthwise.  (Grading 100 unstaples sheafs of paper is a nightmare).  You do NOT have to put your Social Security Number on your papers; that's between you and the Social Security Administration.

As a rule, late homework is NOT accepted.  Under very special circumstances, the grader may, at his discretion, choose to make exceptions.  However, I will not tell him to do so.

Graded homework can be picked up outside of James Rath's office; RLM 11.152
