**Math UN2010 Linear Algebra:** College Bulletin

**Prerequisite**: MATH UN1201 Calculus III, or the equivalent, strongly recommended.

**Textbook**: Otto Bretscher, *Linear Algebra with Applications,* **5th edition** (Publisher link)

This course covers matrices, vector spaces, linear transformations, eigenvalues and eigenvectors, canonical forms, and applications. This course provides and introduction to writing mathematical proofs.

Students who wish to focus on applications and practical approach to problem solving, rather than abstract mathematics and mathematical proofs, should consider taking MATH UN2015 – Linear Algebra & Probability. It is recommended to students majoring in engineering, technology, life sciences, social sciences, and economics.

Students majoring in mathematics should take MATH UN2010 – Linear Algebra.
