Quizzes and solutions:

Here is the quick review sheet that I made up. It is not complete, so you should still make your own quick review of the homework I assigned, the quizzes we took, and the two tests.

  I will always be available during my office hours. In addition, you are welcome to make appointments to see me at other times.

Requirements and grades:

The secret to doing well is to attend class and to read the book. You should read each section before we talk about it in class, then again after class, before doing the homework for the section. If you have any trouble understanding it, read it several times, first, quickly for an overall idea what the section is about, then in detail, working out the examples the book uses to make sure you know why each statement is true. Only after this should you start the homework. You may be pleasantly surprised how much easier the homework is with this sort of preparation. You will certainly understand the material and retain more of it, if you study in this way.

Special attention will be paid to the quality of the writing you turn in. Mathematics consists of logical relations between ideas, not just calculations. Understanding and explaining the logical relationships will make your work easier to do and easier to read.

There will be weekly quizzes each Friday, of about 10 minutes duration, which will help you assess your understanding of the material. The best 10 of these (out of 13) will be counted toward your final grade. The quiz and a solution to it will be posted on Blackboard under Course Documents after the quiz has been given.

Grades will be computed as follows:

Schedule:

Here is a schedule of the exams and the material we will cover.

Test 1	Monday, October 3
Test 2	Monday, November 7
Final Exam	Friday, December 16, 8:00 - 10:30 AM

Each test will cover the material we have done up to that point, and will be preceded by a review day.

Topics:

Chapter 1	Linear Equations, row reduction, solutions, linear transformations.
Chapter 2	Matrices, dimension and rank.
Chapter 3	Determinants.
Chapter 4	Vector Spaces, subspaces, linear independence, spanning, bases, linear transformations revisited.
Chapter 5	Eigenvalues and eigenvectors
	and, as time permits, as much as we can of
Chapter 6	Orthogonality, Gram-Schmidt and least squares.
Chapter 7	Symmetric matrices and quadratic forms.
