### Linear Algebra (MATH-3215)

Linear algebra is the study of linear systems of equations, vector spaces, and linear transformations. Solving systems of linear equations is a basic tool of many mathematical procedures used for solving problems in science and engineering.

Prerequisite

To succeed in this course you will need to be comfortable with vectors, matrices, and three-dimensional coordinate systems.

Learning Outcomes

At the end of this course the student will be able to:

• Solve linear systems of equations
• Comprehend vector spaces, subspaces and inner product spaces
• Understand fundamental properties of matrices including determinants, inverse matrices, matrix factorizations, eigenvalues, orthogonality and diagonalization
• Have an insight into the applicability of linear algebra
• Critically analyze and construct mathematical arguments that relate to the study of introductory linear algebra.
