NOTE: Because of the snow week, both midterm exams will be moved back one week.
The new dates are Thursday, February 26, and Thursday, April 9.

As noted on the syllabus, the text for the course is Introduction to Linear Algebra, ed. 6, by Strang; the section numbers below refer to it.
The style of this book is conversational. In addition to numerous examples, it contains many gems hidden in asides. Keep an eye out for them!

Later in the course I will refer to the supplementary notes and problems at the above links.

Here are some additional free online references you might find helpful:

   Linear Algebra Done Right, by Axler: this text is more theoretical and rigorous than Strang.
   (Strang is more suitable for us because Math 4450 has no proof-based prerequisites.)
   Linear Algebra Done Wrong, by Treil: I just love this book.

Final Exam: Tuesday, May 5, 10:00-12:00

Exam 2: Thursday, April 2 9 (changed due to snow week)

Exam 1: Thursday, February 19 26 (changed due to snow week)
