Advanced Ordinary Differential Equations
Department of Mathematics, University of Toronto, Fall 2012
Agenda: If calculus is about change, differential equations are the equations governing change. We'll learn much about these, and nothing's more important!
Instructor: Dror Bar-Natan, email@example.com, Bahen 6178, 416-946-5438. Office hours: Mondays 10:30-11:30 or by appointment (v).
Classes: Mondays, Tuesdays, and Fridays 9-10 in RW 229.
||Teaching Assistant: Jordan Bell, firstname.lastname@example.org.
Tutorials: Tuesdays 10-11 at RW 229. No tutorials on the first week of classes.
Boyce and DiPrima, Elementary Differential Equations and Boundary Value Problems (current edition is 9th and 10th will be coming out shortly. Hopefully any late enough edition will do).
