**Prerequisite:** Math 141.

**Text:**
Lecture Notes
(These notes maybe updated during the course of the semester.)

**Supplemental texts:**
As the notes above may be too compact at times for many of you and have limited examples only, please purchase (either 4th edition, or much cheaper 3rd ed.)

- Mathematical Proofs, A Transition to Advanced Mathematics by Chartrand, Polimeni, and Zhang.

- How to prove it, a structured approach, 2nd ed., Danniel J. Velleman, Cambridge U. Press, 2006.

** Preliminary Test Schedule:** 1st week of Oct, 1st week of Nov, Dec 7.

You are
required to know the material in the lectures, the notes (even if not
covered in lecture, except as indicated) and in the homework. Only
non-graphing, non-programmable calculators are permitted on exams/quizzes.
You are expected to attend each test as scheduled, unless you have a
documented medical or other valid excuse. IDs will be checked. Contact me
**before** taking an exam if you are seriously ill.

** Quizzes**: There will be a short quiz in each recitation on the recent
material. No makeups will be given, but the 2 lowest marks will be
dropped without penalty.

Additionally, there may be some simple quizzes during lectures.

** Homework:** due in class. No late homework will be accepted. Each homework assignment will
consist of a number of problems, of which only some problems (not
specified beforehand) will be graded. You may work jointly on homework
with your study group or other members of the class, but you must write up the
problems on your own.

** Homework guidelines:**

- Use 8.5" by 11" paper, staple sheets together.
- If you want to protect the privacy of your your homework grade, then keep the first page of your homework empty, except for your name (which must always appear on the first page). Your grade will appear on the second page of your homework.
- Label each homework problem clearly.
- Write clearly and legibly.
- You are encouraged to use computer document preparation system called Latex.

- the best two tests, 100pts each, and recitation quizzes, 100pts, or

- three tests, 100pts each.

360pts (total) including at least 80% on last test guarantees A.

352pts (total) including at least 70% on last test guarantees A-.

The final grades maybe curved. The average Math 311 final grade distribution in the recent years was as follows:

A 25%, A- 4%, B+ 8%, B 18%, B- 9%, C+ 4%, C 14%, C- 5%, D+ 5%, D 6%, F 16%.

Most likely the grade distribution in this class will be similar.

** Incomplete:** Incompletes will only be given for reasons beyond your control, serious illness. You must be passing the course to get an incomplete.
University policy is that if you receive an 'I' grade (incomplete), then you
are also assigned a default grade, which is the grade you have already earned
averaged with a 0 on the remaining work. It is easy to see that even
a good student will normally receive an 'F' as the default grade. This appears
on your transcript, as 'I/F', until you make up the incomplete or 15 months
elapse, when you would receive the default grade (you would receive the F in
this example).

Students who received an incomplete in a
previous 311 class should not register for this class, but must file a petition form with the Math Department.
