II. Differential Equations

( \newcommand{\kernel}{\mathrm{null}\,}\)

The second part of this course is on differential equations. We begin with first-order odes and explain how to solve separable and linear equations. A range of applications
are given. We then discuss the important case of second-order odes with constant coefficients. Homogeneous and inhomogeneous equations are solved, and the phenomena of resonance is discussed. When the coefficients are not constant, a series solution is often required and we discuss this important technique. We next study a system of linear differential equations and show how some of our knowledge of linear algebra can aid in their solution. We finish by considering nonlinear
equations and the ideas of fixed points and linear stability analysis.
