Math 221 - Introduction to Linear Algebra

Spring 2008 - Matthias K. Gobbert

Homework


The assigned homework problems are listed below. This page will be updated throughout the semester if necessary. Watch for announcements in class, by e-mail, or in Blackboard.

Homework is due at the beginning of class on the dates listed. No late homework can be accepted under any circumstances due to the difficulty to communicate with the grader in a timely and orderly fashion. However, the maximum possible score will be reduced by the equivalent of about two homeworks to avoid penalizing infrequent absences.

The chapter and section numbers refer to the text, David C. Lay, Linear Algebra and Its Applications, third edition, Addison-Wesley, 2003 (or updated printing 2006).
