Ordinary Differential Equations

Instructor

Kevin Henriot

Office: Mathematics building, M209
Email: khenriot (at) math (dot) ubc (dot) ca
Office hours: Monday 2:00-3:30 PM, Thursday 10:30-12:00 AM.
Office hours room: Leonard S. Klinck building, LSK300B/LSK300C.

There are replacement office hours for my previous leave this Friday (October 31) in LSK300 from 9:00 AM to 11:00 AM. Lecture notes on Chapters 2 and 6 of Lebl's book may be posted online on Saturday.

Class schedule

We meet on Mondays, Wednesdays and Fridays from 8:00 to 9:00 am, from September 3 to November 28, in room 201 of the Leonard S. Klinck building.

Exams

There are two midterms on October 1 and on November 5, and the final exam will take place on December 15 at 3:30 PM. For the final exam, if a student has an exam conflict or hardship, he should email me so that an arrangement may be found with the math department. An exam hardship is defined as three exams within 24 hours, and an exam conflict can be two exams at the same time, a religious holiday, or another serious problem.

Midterm 1 solution.

Time and location for midterm 2: Usual class time/room, that is Wednesday November 5, LSK201, 8:00-8:50 am.

Content for midterm 2: In Lebl's book, Chapter 2 on higher-order linear ODEs (except section 2.3) and Chapter 6 on the Laplace transform (except subsections 6.2.4, 6.3.3, 6.4.4). A table of Laplace transforms will be made available during the exam.

Practice exams:
2009 Midterm 2, solution.
2010 Midterm 2, solution.
