Textbook: Linear Algebra with Applications, Second Edition, by Otto Bretscher

You should go to section the first week of class even though you have not had lecture yet. You should read Appendix A on Vectors before the lectures start and the Teaching Assistants will go over that material the first week of class.

Syllabus and General facts of life for the course.

For those who want to learn Matlab in relation to this material you can go here.

Exams and some solutions from the Spring, 2003, version of the course are here: Exam 1 Exam 2 Final

Another very nice resource for the course is the web page for the course this summer.

There are a number of really pretty computer aids which can help you get a feel for the material in this course. The tools are at TOOLS. The required plugins used to be located at PLUGINS. but they are not there anymore. Perhaps if you poke around at the next site or on google you'll find what you need. Another web site which might have the same thing in a more, or less, organized fashion: OPTION. These are really pretty neat and if you get them working then you can play with them til your heart's content. The ones which are perhaps most interesting to our linear algebra class are LinearMatrixTrace, LinearParameters, and LinearTransform.

Problem set assignments:

Problem Set Number 1, Due Sept 12.

Problem Set Number 2, Due Sept 19.

I'll post the homework soon but since school is closed Friday, September 19, because of hurricane Isabel, there will be no section, no quiz and no homework due. It is at your own peril that you fail to do the homework even though it is not going to be handed in. Remember, you learn the material in this course by doing the problems. This has been a very important week and if you don't work the problems it will show up later in your understanding of more advanced material. If you had gone to class then the quiz would have been something like this:

In R^3, i.e. 3 dimensional Euclidean space, what is the 3x3 matrix for orthogonal projection to the line generated by the vector (1,1,1)?

As with all quizzes, I highly recommend that you be able to do this.

Problem Set Number 3, Due Sept 26.

Problem Set Number 4, Due Oct 3.

Problem Set Number 5, Due Oct 10.

The Oct 7 exam number 1 is here on the web for future reference. Solutions will not be posted because the exam was worked in class the day after the exam. The class distribution for the grades is here.

Problem Set Number 6, Due Oct 17.

Problem Set Number 7, Due Oct 24.

Problem Set Number 8, Due Oct 31.

Problem Set Number 9, Due Nov 7.

Exam seating assignments and Problem Set Number 10, Due Nov 14.

The Nov 11 exam number 2 is here on the web for future reference. Solutions will not be posted because the exam was worked in class the day after the exam. The class distribution for the grades is here.

Problem Set Number 11, Due Nov 21.

Suggested Problems, Number 12, Not Due Nov 28.

Problem Set Number 13, Due Dec 5.

The final exam is Saturday, December 13, 9 a.m. to noon. It is being held in 3 rooms. Section 2 will be in Krieger 304, Section 4 will be in Krieger 308 and Sections 1, 3, and 5 will be in Krieger 205. Be sure and go to the correct room.

The class distribution for the final exam is here. You, as a class, did very nicely on a difficulty final. Congratulations and keep up the good work!

The final exam is now on the web.
