## MATH 120: Honors Differential Calculus,

Winter term, 2016.

####
Instructor: Joshua Zahl.

Where and when : MTWF 10-11, in Math 102.

My office: Math 238.

e-mail: jzahl@math.ubc.ca

Office hours: M 16:00-17:00, T 14:30-15:30, W 11:00-12:00

Text: We will loosely follow *Calculus Single Variable 8th edition* by Adams and Essex. Previous editions should be fine as well.

### Course Description

This is an Honours course. Emphasis will be on both computation and theory. Course material will mostly be taken from Chapters 1-4 of the text: Limits, 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 returned the following Wednesday at the end of class. The lowest homework score will be dropped.

There will be two in-class midterms. These will be held on **Wednesday, October 5th** and **Wednesday, November 9th**. 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.
