Course Information


For more counting problems and additional techniques, the book "Introductory Combinatorics" by Kenneth Bogart is on reserve in Steacie Library (under Math 2320). This is also a second reference for Generating Functions.

NEW NEW The exam is Thursday Dec 19 at 8:30 AM. It takes place in the three lecture rooms:
Whiteley's section (Section A) will write in CLH C.
Dow's section (Section B) will write in CLH A & B.

Notes on the content for the exam In response to queries: yes the exam will include:

Walter Whiteley will hold an extra 'review tutorial' for Math 2320 on Monday December 16 at 1:30-3:30 in SLH B. This is open to all students in the course.

Friday December 6 at 8:30, a review session will be held in Bethune 218. This is to make up for the class missed on October 25.

The same is true for the 1:30 Section (except the classroom will be our usual one).
