The Prerequisites for Math 315 are: Math 171, 172, 220, and 273. If you have questions about your preparation for the course, please see me soon. In particular, we will be using significant amounts of material from linear algebra such as computing determinants, inverse matrices, eigenvalues and eigenvectors.

Suggested homework problems are given below, however, this homework will not be collected or graded. On the other hand, the Exams will be based upon homework.

There is an instructors manual with solutions to some of the problems on reserve in the Owen Science Library. There are also some of my old Math 315 exams available there.
