# MATH 113 § 1

Welcome to the home page for section 1 of MATH 113 at the University of California, Riverside, in the fall of 2004. I am Toby Bartels, the teaching assistant for section 2. The instructor is Ivan Penkov, and the teaching assistant for section 3 is Jae-Wook Chung. Dr. Penkov's office hours are Wednesday 4:10 to 5:30 and Friday 11:00 to 12:20.

The text is Linear Algebra, Third Edition, by John B. Fraleigh and Raymond A. Beauregard. Topics include: vectors, matrices, and linear systems; dimension, rank, and linear transformations; vector spaces; determinants; eigenvalues and eigenvectors; orthogonality; diagonalization.

## Homework

Homework will be assigned by Dr. Penkov at each lecture. The homework assigned during a given week is always due on Wednesday next week, before the lecture starts. (No homework is accepted after that.) Only some of the problems on each assignment will actually be due.

After Dr. Penkov assigns homework each lecture day, he tells me and I list it here. Indeed, that's the main reason for this web page! The problems are taken from the course textbook.

## Credit policy

The total possible number of points is 110. Each midterm exam, as well as the final exam, is worth 40 points. Your score will equal H + B1 + B2, where H denotes your homework points (H < 30), B1 and B2 are your two best shots out of the midterms and the final, provided your final exam score is 22 or more. If not, B1 is your best midterm shot and B2 is your final exam score. 103 points will earn an A+.
