General 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.

Course Objectives

Upon successful completion of the course, students will be able to:

  1. Find solutions of systems of equations using various methods appropriate to lower division linear algebra;
  2. Use bases and orthonormal bases to solve problems in linear algebra;
  3. Find the dimension of spaces such as those associated with matrices and linear transformations;
