This is an archive of the first 6 weeks of the linear algebra course I taught at Emory University in Spring 2021. I cross-posted all class pages and notes both here and on the Canvas page, but students much preferred Canvas and it got overwhelming to keep two websites up to date so I gave up posting here after the first half of the semester. I hope the incomplete information presented here is still somewhat helpful.
Please scroll all the way down for general information about the course, or click here for a PDF file with the course syllabus and policies.

All of the information presented here (and more) is also available on the Canvas site for this course.)
Other than Canvas, we will use Zoom and Gradescope in this class.
We will use the following textbook which is free to download:
"Linear Algebra with Applications", by W. Keith Nicholson, Version 2019 - Revision A.
The book consists of eleven chapters, we will cover most parts of the first eight chapters.
