## 642:550 Linear Algebra and Applications (Fall, 2013) Homework Assignments

Text: Gilbert Strang, Linear Algebra and its Applications, Fourth Edition
ISBN 0-03-010567-6, Thomson -- Brooks/Cole, 2006.

Caution: Although the text of the International Edition of this book is essentially the same, the problems generally have different numbers; if you use this version of the book you must submit the correct problems. There is a separate document on the course web page that gives the problem numbers for the International Edition.

The Graded Problems in the list below should be handed in at the class meeting on the due date. In addition to being mathematically correct, your write-ups are expected to show a high level of clarity and completeness. You cannot prove a general mathematical assertion by a single numerical example. (Of course, one specific counter-example suffices to disprove an assertion.)

LATE HOMEWORK IS NOT ACCEPTED.

The Recommended Problems do not have to be handed in, but you are encouraged to work all of them (many of them are short, and there are answers in the back of the book for the odd-numbered problems).

Academic Honesty: The homework you submit for grading should be your own solutions to the problems. Do not copy other student's work or allow other students to copy your work.
