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. The material below generally applies to all sections, unless other information has been provided by your instructor.


General information

This course is using UBC's new Canvas system which is gradually replacing the legacy Connect.

Mathematics Learning Centre

There is help available at the MATHEMATICS LEARNING CENTRE (MLC), a drop-in tutorial centre for undergraduate Math courses located in the Leonard S. Klinck (LSK) Building. It is usually open Monday through Friday, check website above for details.

Textbook

We are using "APEX Calculus, Version 3.0, Volume 3 (Chapters 9 - 13)". Hardcopies may not be available from the bookstore, but you can buy them from the author's website or from online retailers in $CAD. An electronic copy of this book is also available online at no cost from http://www.apexcalculus.com.

Homework

There will be two kinds of graded homework: weekly WeBWorK and fortnightly written assignments from the textbook. Both types of assignment will usually be due on Fridays at 11:00 a.m., with the first due on Friday September 15.

WeBWorK assignments can be found here. You will need to log on with your Campus Wide Login. For most problems, you will have an unlimited number of attempts and will not be penalized for incorrect attempts, so you can continue to work until you have it correct. Use the email instructor button for any questions (mathematical or otherwise) regarding WeBWorK. The "instructor" is not your section instructor; it is Nicholas Lai, a teaching assistant helping with WeBWorK.

There will be written homework assignments, due roughly every two weeks at beginning of class at 11:00 on Fridays, which will be graded. The assignments will be listed in the weekly schedule below. Late assignments will not be accepted.

Written homework can be picked up in the MLC.

Optional recommended problems: There will be suggested practice problems from the book and other sources which will not be collected or marked for credit.
You are encouraged to do lots of problems, this is the best way to learn the subject.
There will also be optional WeBWorK, which will not count towards your mark for the course. Initially its due date will be the same as the required WeBWorK assignment. Answers will become available at the due date, and then the optional WeBWorK will reopen until the Final Exam.

Contacting your instructor

Grade change requests: At least for Section 101, 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.

Course Evaluation: Please take a few minutes now and complete the evaluation for MATH 253. Your evaluations really can make a difference. We use your feedback to assess and improve our teaching; Heads and Deans look at evaluation results as an important component of decisions about reappointment, tenure, promotion and merit for faculty members; and evaluations are used to shape Departmental curriculum. Please help us make the course effective by telling us what works well and what can be improved.

Final Exam: The final exam will be based on all topics of the course, with around 50% of the marks devoted to integration.
Here are some old final exams to assist with your studying: 2007, 2009, 2010, 2011, 2012, 2012 Solutions, 2013, 2014, 2014 Solutions, 2015, 2015 Solutions, 2016, 2016 Solutions.
(other solutions are not available). Some solutions need a login; this is the same as the homework solutions.
