**Textbook: ***Linear Algebra*, S.H. Friedberg, A.J. Insel,
L.E. Spence, Third Edition. Prentice Hall, 1999. We will be following the
official syllabus closely, but the presentation will differ substantially
from that in the textbook (relying more on my
own course notes). It's a good idea to read the textbook concurrently
with the course for a second opinion.

**Homework: **Homework will be collected and returned every Thursday
in section meetings, starting on Thursday, October 10; there will be eight
assignments. Each homework will consist of about ten problems of varying
difficulty (both computational and theoretical), about half of which will
be from the textbook. The exact questions will be available on the Web,
and also handed out in lectures. Only three of the questions, chosen at
random, will actually be graded, however it is strongly recommended that
you attempt all the questions in the assignment.

Solutions to each homework will be available on the Web on the evening of the due date. Late homework will not be accepted.

**Examinations: **There is one mid-term, on Friday, Nov 1, 1-2pm,
at MS 5127, and a final examination on The final is at Tuesday, Dec 10,
8-11 a.m (exam code 06), at a room to be announced.

**Grading: **The final grade is based on the homework (15%), mid-term
(35%), and the final examination (50%).

If you cannot make one of the examinations, contact me as soon as possible, preferably one week in advance of the exam. Retroactive, or last-minute requests for a make-up, will most likely be denied.

**Calculators and written materials: **You may use whatever resources
you wish to do the homework, including calculators, textbooks, friends,
TAs, etc., although by the end of the course you should be able to do all
the homework questions without any assistance. No calculators or texts
will be allowed in the mid-terms and finals, but a 5x7 index card will
be permitted for each exam. More information on examination procedures
will be given later in the course.

**Mathematical level: **The emphasis in this course is theoretical,
including abstract proof-type questions in the homework and in the exams.
For most of these questions, a relevant sequence of equations arranged
in an intelligent and logical order, accompanied by a few words of explanation
at the critical steps, will be sufficient.
