## Textbook

The official textbook for Math 2185 is *Linear Algebra, 5th edition* by Stephen H. Friedberg, Arnold J. Insel, and Lawrence E. Spence. Access to this book will not strictly be required but it will be a useful reference throughout the course. As of the time I’m writing this, there appear to be cheap paperback copies on Amazon.

There are other excellent references you may find helpful. Linear Algebra Done Right, and the new fourth edition is freely available. A similar, freely available book is Linear Algebra Done Wrong by Sergei Treil.

For a more geometric and computational perspective, you may find the online source Interactive Linear Algebra very helpful. It has many manipulable graphics that can help you develop geometric and algebraic intuition.

## Course Goals

This is our rigorous, proof-based linear algebra course, intended for math majors and students in other majors (e.g., computer science, data science, economics, or statistics) who want a deeper conceptual understanding than is offered in Math 2184. Math majors, prospective math majors, and students who intend to take Math 3125 should be encouraged to take this course. The theory of vector spaces is developed from the axioms and linear algebra is studied over arbitrary fields (with an emphasis on \(\mathbb{R}\) and \(\mathbb{C}\) in examples). This allows students to work with important vector spaces in addition to \(\mathbb{R}^n\). Linear transformations also take a more central role than matrices, with matrices serving as a computational tool in the finite-dimensional case.

Complete proofs of most results are presented, and students are expected to develop a mastery of proving results in linear algebra. As Math 2971 is a corequisite (or prerequisite), it is appropriate to include brief discussions of proof techniques when relevant. In addition to conceptual understanding, the course also emphasizes both the computational and geometric aspects of linear algebra.

This course is part of a two-course sequence, along with Math 3125 (Linear Algebra II), which further develops the theory of linear algebra, but also covers applications to statistics, computer science, and physics. The comprehensive introduction to linear algebra given in Math 2185 prepares students to fully understand the mathematics behind these applications.
