MATH 120: Honors Differential Calculus,

Winter term, 2018.

Instructor: Joshua Zahl.
Where and when : MTWF 10-11, in WOOD 4.
My office: Math 117.
Office hours: M 11:00-12:00, T 13:00-14:00, W: 16:00-17:00
TA office hours: R: 14:00-15:00, LSK300C
Text: We will loosely follow Calculus Volume 1 by Tom Apostol.

Course Description

This is an Honours course, with an emphasis on theory. Course material will mostly be taken from Chapters I, 3, 4, 6, 7, and 8 of Apostol: 1-4 of the text: The real numbers, Limits and continuous functions, Differentiation, Elementary functions, Applications and Approximation.

Grading policy

The course mark will be based on weekly homework assignments (20%), two midterms (40%), and a final exam (40%).

There will be weekly homework assignments, which are due Friday at the beginning of class. Graded homework will be available for pickup at the Math Learning Center, which is open 11am - 5pm Mon-Fri. The lowest homework score will be dropped.

There will be two in-class midterms. These will be held on Wednesday, October 3rd and Wednesday, November 7th. Please make sure you do not make travel plans, work plans, etc., without regard to the examination schedule in this class. There will be no make-up or alternate exams. If you miss a midterm, your score will be recorded as 0, unless you have a serious documented reason (an illness, a death in the family, etc.), in which case you should discuss your circumstances with the instructor as soon as possible, and in advance of the test.

The final exam will be held on December 4 at 8:30 am in SWNG 121.
