Classes
Monday, Wednesday, Friday, 2:00-2:50, Fenton 218. In lieu of the Tuesday class some
additional reading will be assigned.
Office Hours
Monday 5-5:50, Tuesday 5-5:50, Friday 3:00-3:50 (Deady 309)
or by appointment.
Exams
Final - 50 minute exam on 3:15-4:05 of Tuesday of the Finals week.
50 minute midterms - Wednesdays of the 4th and 8th weeks (tentatively).
Quizzes - Wednesdays of the 2nd, 3rd, 6th, and 10th weeks
during the first 20 minutes of the regular class hours (tentatively).
Homework
There will be weekly homework assignments posted on
Wednesdays on this site
(see below). On the
same day the previous homework will be
collected. The homework will be graded and returned in a week also on
Wednesdays (in the ideal world).
The homework assignments may be your most important resource in the course. They will
generally be quite difficult, and the places where you get stuck should indicate to you where
you need help. It is a good idea to start the homework as soon as possible - better 1 hour
every night for 5 nights than 5 hours all at once.
Grades
I will determine your course grade by the following weights. Homework - 20%, Quizzes -
20%, 50 minute exams - 20% each. The curve will vary from test to test and
will depend on the average performance of
the students. The curve for each test will be announced after that test. The
curve for the homeworks will be standard: A: 90%, B: 80%, etc.
Note that normally I give maximal points for a problem only if it is solved
entirely correctly (except perhaps some minor arithmetic mistakes) and give less points than
usual for a partial or wrong solution.
Also, I tend to give quite difficult (or, rather, non-standard) problems. I think this
produces a more just distribution of the points between the students. As a result the average
points (but not the final grades) in my classes are usually lower than those you
might be used to. If you have, say, 60% for the midterm it does not mean that you have
a "D" (sometimes this might be an "A+"). If you have any questions on how you are doing in the
course do not hesitate to come to my office and
ask. Please, do the same if you think that some of your tests or homeworks were graded
incorrectly (mistakes do happen).
Make-ups
Make-ups for quizzes and exams will not be given
and the late homeworks will not be accepted unless you have a documented
excuse. If you miss a
class, it is your responsibility to find out what happened in that class.
Prerequisites/Course Content
The prerequisite for this course is
Math 252.

Applied Linear Algebra and Matrix Analysis by
