COURSE DESCRIPTION

This course provides a rigorous introduction to the study of ordinary differential equations, linear algebra, and a brief introduction into partial differential equations. Students will learn the basic techniques for understanding and solving differential equations that arise in applications.

MATERIALS

Martin Braun, Differential Equations and Their Applications, 4th Ed
Gilbert Strang, Linear Algebra and Its Applications, 4th Ed

The full syllabus, notes, announcements, etc. are available on the course Canvas page.
