Steven J. Leon, * Linear Algebra
with Applications,* Sixth Edition, Prentice Hall, 2002. It is
highly recommended that you attempt a preliminary reading of the text book
material before it is covered in lecture, and then read it thoroughly again
after the material is covered in lecture!

The
textbook's web site has some interesting sample problems, and interactive
true/false exams.

The web
pages from my Winter 2003 Math20F course include past quizzes, midterms and final
exams.

**Section meetings:
** Thursday section meetings begin
April 3, I think (

Tuesday section meetings begin April 8, and the first computer assignment is due that next week. Tuesday sections cover the Matlab assignments. You are not required to attend the Tuesday section in which you are enrolled.

**Lecture topics. **
A list of the topics covered in the lectures
(usually updated a day or two **after** the lecture).

**Homework assignments. **
Written homework assignments from the text book.

We do not yet know if these can be
graded; however, you must do them and hand them in.

Homeworks are to be handed in weekly
in the Friday lecture. You can discuss them in the Thursday section
meetings.

**Matlab assignments. **
Weekly computer assignments, Tuesday sessions, due
Thursday in section.

Computer lab sections held Tuesdays,
in the CLICS lab, upstairs in Galbraith Hall mezzanine (northwest corner).

Common list of assignments for all
Math 20F lectures.

Liz Fenwick and Sam Buss have Matlab
on their office computers and can help with Matlab assignments during regular
office hours.

**Quizzes. **
Quizzes held most weeks on Thursday, on preannounced topics, and take approximately 15
minutes.

First quiz is Thursday, April 10
(second week).

Quizzes will be held in the last 15
minutes of the Thursday section meetings, unless your TA alters this.

You may drop your lowest two quiz
grades.

The quiz topics will be announced in
class one or two lectures in advance.

**Midterm exams. **
50 minute long exams -- during a regular lecture hour.

**Midterm #1**: Monday,
April 28. Test with answers available in PDF and
postscript formats.

**Topics:**

only for the midterm. No "cheat sheet" or notes or text or calculators
allowed. Blue books are not needed.

**Midterm #2:** Friday,
May 23. Test with answers available in PDF and
postscript formats

**Topics:**

**Skills
study** sheet. Available in PDF and

**Review

You may bring
a single 8.5x11 sheet of notes. No other text, notes, calculator, etc. may be
used.

Please bring
student ID with photo.

**Grading. ** The final exam and the two midterm exams
will count the most: 40% for the final, and 20% for each of the two midterms.
The quizzes and lab assignments, and homework assignments will each count for about 5
to 8% of the course grade. (Percentages are only approximate and are
subject to minor changes.)

Although the percentages for homework assignments, quizzes
and labs are low, they are a required part of the course. If you
completely omit doing the Matlab assignments, for instance, then your grade may
be reduced beyond the indicated percentage.

**Identification. ** We have a large
class, and it can be difficult to keep track all the grades. Please label
all assignments and exams with (a) **your name, **(b) **your student ID
number,** and (c) the time of the section that you attend (so we can
return it to you). If you prefer to use a name different from that in the
official UCSD records, please put both versions of your name! Poorly
labeled assignments may receive reduced credit or even no credit.

**Academic integrity.** Academic
integrity is very important, and if cheating is detected (particularly on exams)
it will treated seriously, possibly including referral to a dean.

For homework problems and computer lab work, it is permitted
to work with other students or in groups or to get help from a TA or instructor,
**but** you should write your solutions on your own. If someone shows
you an answer to a homework problem, you should wait at least 10 minutes and
then try to write up the answer on your own. This is to be sure you are
really learning the homework material! If someone helps you with a
computer lab, you should be sure that you **do all your own typing**, and
that you understand how to do it.
