Math 225: Ordinary Differential Equations
The study of differential equations is pretty
awesome-possum, but there is far more material than can be stuffed into
a one semester course. On this website you will find a bunch of extra
gooddies that I've put
together especially for my recitations.
Some slide you might have seen during the semester.
Here are some review materials I've slapped together. Good luck!
I've made all the code demonstrated in class available here.
(A Python script comparing a few numerical methods.)
(M-file that defines the ODE's for the coupled spring-mass system.)
(Use this, and the above m-file to plot the normal modes of the coupled
(Solves the second order ODE with constant coefficients.)
(A tool for exploring beats and resonance.)
Here are links to some helpful online resources.
