Information about the textbook, the topics, the marking scheme, and policies can be found in the Course Outline.
A detailed weekly syllabus is given below.


General information

This course is using UBC's new Canvas system

Textbook

We are using "APEX Calculus, Version 3.0, Volume 3 (Chapters 9 - 13)". An electronic copy of this book is available online at no cost from http://www.apexcalculus.com.

For further exercises to practice we also recommend Multivariable Calculus, Stewart, 7th Ed. Having this book is NOT mandatory and is only meant as a source of extra excercises. These will not be collected nor marked for credit.

Homework

There will be five written homework assignments, due on Thursdays (May 24/31 and June 7/14/21) by the beginning of the lecture.

Contacting your instructor

Grade change requests: Any requests to reconsider grades (homework, midterm, etc) should include the regrade request form.

Email sent without "253" in the subject is very likely to be ignored.

Lecture notes

Lectures notes come in chronological order, but they do not correspond to each lecture exactly. Check the syllabus for more details.

The notes are loosely based on a set of lecture notes by Slade.

General tips

You are encouraged to do lots of problems, this is the best way to learn the subject.

Homework will include material up to the last Friday before the due date. Do not leave it for the last moment.
