This is a one semester introduction to ordinary differential equations. In the first half of the course we will cover the theory of first and second order scalar equations, including the Laplace transform and numerical methods. The second half will be devoted to first order systems, both linear and nonlinear.

Differential Equations, by Polking, Boggess and Arnold. This book comes packaged with another book about using Matlab to solve differential equations (at no additional charge!). Occasionally I will cover topics which are not in the text or present a different approach to some topic.
