# Textbook

J. Rogawski, Single Variable Calculus, late transcendentals, 3rd Ed., W.H. Freeman & CO

Owning a copy of the textbook will be very helpful and is recommended however you might not find it necessary.

## Homework

Solving problems on your own is one of the most important parts of this course. It will teach you how to apply your new knowledge and also be the best preparation for the midterms and final exam.

I encourage you to discuss the problems in teams but write up the solutions on your own. Simply copying your homework will not prepare you for the exams at all and is also not allowed (i.e. considered academic misconduct/cheating).

Hint: You can use Piazza to find teammates!

Every week you will be able to find a list of problems in the lecture schedule. They will be covering the material of the lectures and similar to exam questions.

Certain problems will be your homework which you will have to hand in during the lecture every Friday. Your homework has to be submitted in a form obeying the following rules:

• In the upper right corner of the first page put:

 First and last name Student ID Date, Homework number TAs name Number of discussion session 

• In the upper right corner of every additional page, put your name.
• Staple your homework.
• Write legible. No crumpled, torn paper.
• Label each solution with the section and problem number (e.g. 7.2 #2).
We will not accept your homework if it violates any of the above rules.

# Exams

There will be two midterms and a final exam. Apart from the exceptions mentioned below, only writing equipment will be allowed in exams. Exams must be written in pen.

• Midterm 1: 2-3pm Friday, 2 February, 2019
• Midterm 2: 2-3pm Friday, 1 March, 2019
• Final Exam: 3-6pm, Tuesday, March 19, 2019

Cheatsheets: For each exam, students may bring a cheat sheet. Each student must prepare their own handwritten cheat sheet. For the midterms, the cheat sheet may consist of one side of half a standard (A4 or letter) sheet of paper (i.e. A5 or letter folded in half lengthways). For the final, the cheat sheet may consist of one side of a standard sheet of paper. Cheatsheets that do not meet these requirements will be confiscated at the beginning of the exam.

Calculators: You may use a non-programmable, non-graphing calculator in exams. Calculators not meeting this specification will be confiscated.

Study: Here I will post some practice exams which might aid your study.

The midterm scores will be adjusted to account for any difference in difficulty. Your final grade will be calculated using the maximum of the following two grading schemes. Your letter grade will then be determined by your rank in the class. Unless something very out of the ordinary occurs I expect to give approximately 20-30% A’s and 55-65% A’s and B’s combined.

Option 1:

10% (7 best homework scores) +
40% (combined midterm scores) +
50% (final exam score)
= raw final grade


Option 2:

10% (7 best homework scores) +
30% (best midterm score) +
60% (final exam score)
= raw final grade


Effectively, this will mean that unless you score worse in the final than both midterms, your lowest midterm score will be dropped. This also means missing one midterm probably will not impact your grade in any serious way.

## Questions and Help

Mathematical questions should be asked on Campuswire. Click here to sign up, then search for the course. You can either do so anonymously or with you full name. You are also encouraged to answer or take part in the discussion of the questions of others!

Obviously homework questions and solutions should not be posted on Campuswire. Offences will be treated as academic dishonesty/cheating.

You can also visit me and the TAs in our office hours.

Administrative questions should in the first instance be directed to your TA. If your TA cannot resolve your query then you should contact me.

If you need to email me, the subject line must include the string math31. If not, then there is a good chance your email will slip through the cracks and remain unanswered.

You can get additional help from the Student Math Center, where undergraduate math majors as well as math graduate students will be able to help you.
