Textbook: Applied Linear Algebra, 2nd edition, by Lorenzo Sadun.
Do not get the first edition! The first edition had a huge number
of printing errors, the second edition has a lot of new content, and the
second edition is priced at about half the first edition.
Prerequisites: M340L or M341 or permission of
Syllabus: Chapters 1 through 7, plus part of 8,
with occasional skipped
sections. You can find an online day-by-day schedule
Homework and attendance:
Homework will be due in class every day, except
for exam days and the first day of class.
See hw.html for the latest assignment.
Late homework will not
be accepted, even a few minutes after class is over,
unless you are sick or have made prior arrangements with me.
In other words, you must attend class every day! Of the 22 assigned
homeworks, I will drop your lowest two scores
(everybody gets a couple of mulligans!) and average the rest.
Exams: There will be two in-class midterm exams, on
Monday July 25 and Friday August 5, plus a final exam on Monday morning,
August 12, 9-12.
These exams will all
be closed book. However, each student will be allowed to bring a single
``crib sheet'' (2-sided) to each midterm, and 2 crib sheets to the
These notes must be HANDWRITTEN ORIGINALS - NO XEROXING ALLOWED.
Grading: Each midterm counts 25%. The final exam counts 50%.
The homework, taken together, counts 25%. At the end of the term I will
drop your lowest 25%. The final grade distribution is neither a straight
scale nor a fixed curve. The cutoffs will be set at the
end of the semester, based on overall class performance, with the
following qualitative standard for the major grades (with obvious
adjustments for plusses and minuses):
An "A" means that you understand the ideas of the course well enough
that you can use them even in unusual settings.
A "B" means that you can do the standard problems we have done during
the semester, but can't do anything new.
A "C" means that you understand the techniques of the class well enough
to handle a (hypothetical) class that has M346 as a prerequisite. (I don't
think there is such a class, but the concept still makes sense.)
A "D" means that you have learned a substantial amount, but that you are
not prepared to take that (hypothetical) successor course.
An "F" means that you have failed to grasp the essential
concepts of the course.
Grading isn't an exact science, and all I'm going to do is adjust
cutoffs. Nobody will leapfrog anybody else. If you have more points
than your buddy, then your grade will be at least as good as your
buddy's, no matter what my general impressions of the two of you are.
Furthermore, a 90% average will guarantee you at least an A-, an 80%
average a B-, and a 70% average a C-. Most of the time, my cutoffs are
a lot more lenient than that.
