Schedule of Lectures
Linear Algebra and its Applications, 4th ed., by David C. Lay.
Expected Background:Officially, the prerequisite is Calculus II. In reality, we will rarely use calculus; almost everything in this class is accessible with only a pre-calculus background. On the other hand, this course will require somewhat more mathematical sophistication than the calculus courses you have probably taken, and will involve more proofs and disciplined conceptual thinking. Ideally, you have seen vectors before and have done some basic operations with them (adding, subtracting, multiplying by scalars). If not, please let me know. More generally, if you have any questions concerning your background, please speak to me as soon as possible.If you fall too far behind in this course, it will be very difficult to catch up. Please see me if things stop making sense!
Mondays 3:30-4:30, Wednesdays 10:00-11:00. Kerchof Hall 208 (my office). If these times do not work for you, please make an appointment with me.
Homework will be due on Wednesdays. It is due in class If you are going to miss class for whatever reason, you must either submit the homework to my mailbox in the mailroom of Kerchof Hall before the beginning of class, or have a friend submit your homework in class. Late or improperly submitted homework will never be accepted. If you know in advance you will be unable to turn in homework when it is due, you should plan to turn it in ahead of time. If you have a conflict with a religious holiday, you must give me advance notice. I will drop your lowest homework score to allow for missed assignments or for assignments that pose special difficulty.
Homework must be neat, well-organized, and legible. In addition, it must be stapled or paper clipped
(no folding over the top-left corner or anything like that). Please
write in paragraphs, sentences, and English
words (oh my!) when they are called for. Many problems will
require you to write an explanation. The grader should not have
to decipher what you are doing--you should be clear and
unambiguous about your methods on a homework problem.
Homework will be graded and every effort will be made to hand it back promptly. Grades will be posted on UVaCollab.
Schedule of Homework (the homework assignments themselves will be posted on UVaCollab)
Midterms will be in class on Wednesday, October 2nd and Monday, November 11th. If you have a conflict with one of these days, you must let me know now. Another exam on the same day is not considered a conflict.
The final exam is (tentatively) on Wednesday, December 11th, from 2:00PM-5:00PM.
Calculators are not permitted on exams.
20% Homework (not all homeworks are worth the same number of points. See the homework schedule)
20% Each Midterm
40% Final Exam
It is possible for exceptional class participation to be factored into the homework grade.
