### Course Description

The course covers Chapters 1-7 from the textbook: linear equations, vector spaces, matrices, linear transformations, determinants, eigenvalues, eigenvectors, etc.

MAT 331 meets for three hours of lecture per week.

### Prerequisites

Students must have earned at least a "C" in a course equivalent to MAT 271-Foundations of Higher Mathematics before enrolling in this course.

### Objectives

After completing MAT 331 the student should be able to
• solve systems of linear equations
• add, multiply matrices
• find the inverse of an invertible matrix
• evaluate determinants
• work with vectors
• identify bases of vector spaces
• find eigenvalues and eigenvectors of linear transformations

### Expected outcomes

Students should be able to demonstrate through written assignments, tests, and/or oral presentations, that they have achieved the objectives of MAT 331.

### Method of Evaluating Outcomes

Evaluations are based on homework, class participation, short tests and scheduled examinations covering students' understanding of topics that are covered in MAT 331.

### Academic Integrity

The mathematics department does not tolerate cheating. Students who have questions or concerns about academic integrity should ask their professors or the counselors in the Student Development Office, or refer to the University Catalog for more information. (Look in the index under "academic integrity".)

### Accomodations for Students with Disabilities

Cal State Dominguez Hills adheres to all applicable federal, state, and local laws, regulations, and guidelines with respect to providing reasonable accommodations for students with temporary and permanent disabilities. If you have a disability that may adversely affect your work in this class, I encourage you to register with Disabled Student Services (DSS) and to talk with me about how I can best help you.
