Office hours: Monday 2:00-3:30 PM, Thursday 10:30-12:00 AM.
Office hours room: Leonard S. Klinck building, LSK300B/LSK300C.

I am away (at mathematical conferences) from October 1 to October 10. The midterm will still take place and the lectures will be covered by Uriya First. There are no office hours during this period, but I will answer all your questions by email.

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 between November 29 and December 17.

Time and location for midterm 1: Usual class time/room, that is Wednesday October 1, LSK201, 8:00-8:50 am.

Content for midterm 1, October 1: In terms of the course outline, the midterm covers all of Part 1 on first order ODEs, and Part 2 up to and including constant-coefficient second-order linear ODEs in the case of real roots. This corresponds to lectures 1-10, and to section 0.0 to just before 2.2.1 in Lebl's book, together with Braun's notes on exact equations.

Recommended preparation for midterm 1: understanding the theory from the lecture notes and textbooks, doing/redoing exercises from homeworks 1--3 and the course textbooks, attempting the practice exams from 2009 and 2010 (note: these sometimes covered more topics than this year).

2009 Midterm 1, solution.
2010 Midterm 1, solution.

Homework

Homework is due weekly (outside midterm weeks) on Wednesdays, before the beginning of the class.
Homework 1, solution, September 17.
Homework 2, solution, September 24.
Homework 3 is due on October 8.
