Linear algebra is absolutely fundamental for further mathematics and its applications. We will cover all basic concepts such as vector spaces, matrices, linear transformations, eigenvalues, determinants and quadratic forms. This is a subject of great practicality in which a certain higher level of mathematical abstraction also appears.

If you own the 3rd edition, I (reluctantly) recommend you buy the 4th anyway. You can sell the 4th at the end of the semester and get some of your money back. There are many altered homework problems between the two editions.

Apart from a few supplements from me, and MATLAB work, the reading and homework will be from this book (most of Chapters 1-7). There is a day by day schedule of work on the course page. Calculators will not be permitted on quizzes or exams.

- 100 points Quizzes

- 100 points MATLAB

- 300 points 3 Semester Exams (100 pts each)

- 200 points Final Exam (Cumulative)

Homework from the textbook will not be collected and graded.

Learning linear algebra without doing homework is like learning to play the piano by watching someone else play. It doesn't work.

Quizzes in sections will usually be from assigned homework (perhaps with slight modification).

Also, exam problems will be heavily influenced by homework.

Please be responsible for your learning, and do the homework. Past TAs for MATH 240 told me their students' grades were well correlated with whether they did the homework. Likewise:

Lay is an incredibly meticulous writer who tries to make the subject as easy as possible. If you read the text and handouts, you can prosper in 240 without the lecture -- but the lecture without reading isn't enough.

A section meeting (apart from a quiz) may involve your asking your TA questions, such as homework questions. (Then, questions concerning material of the lecture the day before will have priority, to encourage you to keep up.) Your TA may choose on some days other activities, such as small group work. Everyone will have good reasons for missing some of the many quizzes. That is addressed as follows: I'll drop the lowest two quiz scores. If you have legitimate reasons for missing MORE than two quizzes, talk to me and/or email me about it.

- Don't fall behind. Make a regular schedule of work.
- Make friends. Help each other.
- Do the homework. You learn by doing, not watching.
- It is important to ``understand''. It is harder in the beginning to work to the point of understanding, but over time, it makes everything easier.
- Do sample and TESTBANK exams for practice before tests.
