# Intro to Linear Algebra

Textbook: Here are the Online Course Notes. For supplementary reading I recommend Gilert Strang's Introduction to Linear Algebra (any edition).
Office Hours: Tuesdays 3:30-4:30 and Wednesdays 2:00-3:00 Here is the course syllabus. Here is an article by Alan Tucker (1993) on The Growing Importance of Linear Algebra in Undergraduate Mathematics. Quote: This author is personally a bit frustrated that calculus gets all of the first year and half of the second year of the lower-divison core mathematics sequence. Hopefully early in the next century, there will be a 'redistricting' of the lower- division mathematics sequence and linear algebra will get equal time with calculus. | ||
