There will be a weekly homework
assignment due on Thursdays at the start of class. The
homework is the most important part of the course as most of your
learning will take place while doing it. We will not
accept late homework except in very unusual circumstances. We
will, however, drop the lowest homework grade.

exam, Monday 24th April.
Calculators, books, notes etc are not permitted in either exam.
Please bring your student ID
to both exams.
Please note that there are no make-up or alternate exams, so make
sure you do not make travel plans, work plans etc that will

any consideration is to be taken for a missed midterm.
Your grade will be based on the homework (10%), the midterm (30 or
40%), and the final (60 or 50%), whichever gives you the best grade.
Since this is a Mathematics Majors course, there is a
median grade of around 68% and students will be expected to
perform calculations and construct rigorous proofs involving
fundamental ideas of the course.
Working together and academic integrity
Homework: We have no objection to collaboration on the homework,
provided that it is done in a way that maximizes the benefit of the
homework to all people involved. It is our experience that you get
- maximum benefit from a homework problem if you work hard on it
alone before combining your ideas with someone else's,
Regardless of whether you arrive at solutions in collaboration with
others or alone, the paper that you turn in with your name on it
should represent your own solutions, written in your own words.

In particular, you may not simply copy someone else's homework
and turn it in as your own. Similarly, copying solutions

These will all be treated as a violation of UBC's Academic
Code. We take academic integrity very seriously and
will follow university procedures in all cases of suspected
cheating - disciplinary
measures can result in expulsion.
Exams: There is anecdotal evidence that quite a bit of cheating
occurs on campus. In an effort to prevent one common form of
cheating, we will xerox a random sample of exam books before
Use of cell phones (in any manner), laptops, smartphones, tablets
and other electronic devices during class is highly inappropriate,
as it is distracting and disrespectful to fellow students and the
instructor. Chatting with neighbours, even when whispered, is
equally inappropriate. If you have a question then please ask the
instructor so the whole class may benefit too.
Arriving late and leaving early is also discouraged. If it happens
then please enter/leave the room silently and do not disrupt the
other students or instructor. Thank you.
