Course Description

This course develops the techniques and theory needed to solve and classify systems of linear equations. Solution techniques include row operations, Gaussian elimination, and matrix algebra. Investigates the properties of vectors in two and three dimensions, leading to the notion of an abstract vector space. Vector space and matrix theory are presented including topics such as inner products, norms, orthogonality, eigenvalues, eigenspaces, and linear transformations. Selected applications of linear algebra are included.

Conditions of Enrollment

Satisfactory completion of: MATH 1B Recommended successful completion of Math 1C. Math 1C introduces vectors and a large part of Math 3 will be about vectors and vector spaces. Moreover, Math 1C (formerly Math 2A) was the prerequisite for Math 3 before the revision.
