Tutoring is available in ASB-B 108 (below math dept)


We will be starting by exploring the ways in which we usually solve several equations at once and then learn how to use matrices and linear transformations to do that, and the properties of determinants that are key to understanding matrices and transformations. Finally we will see how the more abstract setting of vector spaces will help us understand matrices and transformations deeper, providing more powerful tools to solving systems of equations.

Ch. 1 -- sec 1-9 ; Ch. 2 -- sec 1-9 ; Ch. 3 -- sec 1-3 ; Ch. 4 -- sec 1-7 ; Ch. 5 -- sec 1-3 ; Ch. 6 -- sec 1-4; Ch. 7 --sec 1-4.

Quizzes, Tests, Grades, and all that stuff
Practice problems will be given every class. It is your responsibility to be aware of them, either by attending class or by talking to students. You are strongly encouraged to form a study group of students from this class. It is highly recommended that you meet with students in your study group atleast once a week. The problems will help you prepare for the quiz, which will be given almost every week. No make-ups will be given. You are strongly encouraged to talk to me during office hours. The quizzes, while easier to get points than the tests, are crucial to understanding the material and also to preparing for the tests.

Old Exams

There will be 3 in-class tests apart from the departmental final exam. The dates of the tests are given below. No make-ups will be given. The best 2 scores out of the 3 tests will be included in the final grade.

The quizzes will count for 300 towards final grade. I will drop the two lowest scores in the quizzes

Total: 700 points (Quizzes: 300, Tests: 200, Final: 200 )
A: 630-700
B: 560-629
C: 490-559
D: 420-489
F: Below 420
