Attention! Read instructor's comments next to the link to the Tue, June 27 class notes. "Chromatic polynomial" problem due Monday, July 3.


Online text by instructor: Discover Linear Algebra

Note: our point of view will be quite different from that taken in Math 19620 -- Linear Algebra. Nevertheless, I recommend the text used in that course, by Otto Bretscher, as a helpful supplement.
