**Overview:** This course is an introduction to the modern theory of differential equations from both theoretical and applied viewpoints. We will learn how to solve explicitly a wide variety of differential
equations, and how to predict the qualitative behavior of those equations that cannot be solved in closed
form. We will also see how differential equations can be used to model and predict diverse scientific phenomena.
Topics will include basic first and second order equations, existence and uniqueness of solutions,
linear systems, power series solutions.
