Math 306: Honors Differential EquationsCourse DescriptionThis course is an honors introduction to differential equations. We will cover most of the material from the standard course as well as some additional topics. Our primary focus will be on studying linear systems and then using this knowledge to study the qualitative behavior of nonlinear systems. Lectures are Monday and Wednesday 121:15 PM in Krieger 308. Section meets Friday 1212:50 PM in Krieger 308.
Problem sets will be due in class on Wednesdays  see the schedule below for dates. No late homework will be accepted. The lowest homework grade will be dropped.

ExamsThere will be three exams. Two in class midterms and a final.ComputingWhile not essential to the course, being able to plot solutions with the help of a computer can greatly assist in your understanding. As a Hopkins student you are entitled to a free copy of Mathematica which has all the tools (and more!) to do so. Instructions on how to obtain your copy are here. If you want to use something with a less steep learning curve, you can find an online java applet which plots slope fields and solutions is here. See this page if you are having problems running the applet.
