This course contains an introduction to ordinary differential equations. It will cover various kinds of first order equations and then second order equations with constant coefficients.
A knowledge of integration is ESSENTIAL for this course. Please look at your first year and second year notes for reference.
There are 2 lectures per week: Wednesdays at 1pm in Physics Hall and Thursdays at 1pm in Hall F.
The exam is 90 minutes and will take place in January. News forum
