Linear Algebra

Course Description and Grading Breakdown
In this course we will discuss systems of linear equations, vectors and matrices, determinants, vector spaces and linear transformations, inner product spaces and diagonalization.
The prerequisite is Math 1a.
There will weekly homework assignments, a midterm and a final exam. The pass-fail line will depend on a composition of these factors; homework will be worth 40% and the midterm and final will each be worth 30%. Typically the pass-fail line has been at approximately 60%. Those with high scores on the homework and midterm will be excused from the final. To be excused from the final, you will need about 90% of the possible points on both the homework and midterm.

Course Policies
Please go to the recitations. Each week, a portion of the recitation will be dedicated to introducing some computational (or even theoretical) aspect which the instructor will not have time to present in class. In general, get to know your TA, ask questions, and try to fill in all the gaps in your understanding.

Homework is due Mondays at 2:00 pm and will be posted on the course website at least a week before it is due. Please submit your homework to the Math 1 drop boxes on the first floor of Linde. These are the same drop boxes that were used for Math 1a. All problems may be done in collaboration with others. However, each student must write down the solutions in their own individual way. There should be no two identical solutions to any problem. Collaboration is not allowed in the exams. Please consult the collaboration table for more information about what is and is not allowed.

At most, one late homework set will be accepted, and only at the discretion of the head TA. Arrangements should be made in advance with the head TA and the work should be submitted less than 1 week late, except in extreme circumstances. Beyond that, late homeworks will NOT be accepted, except with a note from the Dean's office.

* You may use a computer or calculator while doing the homework, but may not refer to this as justification for your work.  For example, "by Mathematica" is not an acceptable justification for deriving one equation from another.  Also, since computers and calculators will not be allowed on the exams, it's best not to get too dependent on them.
