Description:

This text Linear Algebra is free for downloading. It covers an undergraduate first course, with a prerequisite of Calculus I. You can use it either as a main text, or as a supplement to another text, or for independent study. Its approach is developmental. Although the presentation is focused on proving things and covering linear algebra, it does not start with an assumption that students are already able at abstract work. Instead, it proceeds with a great deal of motivation, and many examples and exercises that range from routine verifications to (a few) challenges. The goal is, in the context of developing the usual material of an undergraduate linear algebra course, to help raise the level of mathematical maturity of the class.
