Homeworks - 20%, 2 Midterms - 20% each, Final - 40%

There will be 12 homeworks. The best ten will be counted towards
the grade. ** There is no late submission of homeworks. **

** There will be no make-up exams.** The lower of the scores on
the midterms will be
replaced by the final exam marks (divided by two) or the other mid term score if it helps. This is also applicable
in the event of a missed exam (where the missed exam will be counted
as 0 points). To pass the
class, you have to take the final exam.

If you are a disabled student (with or without a document from the Disabled Students' Program) and require special accommodations of any kind, please e-mail the instructor as soon as possible, and no later than September 10.

If you are representing the university on some official duties (say if you are an athlete or in a band), and if there is a conflict with any of the mid-terms, please let the instructor know before September 10.

To do well in the course, it is important to be able to understand as well as write proofs. It might be useful to read Prof. Hutching's article on mathematical reasoning.

Most of our proofs will use standard set theoretc notation. Here are some notes from Prof. Bergman on set theory.

We will also often use mathematical induction. Here are some notes on that by Prof. Bergman.

Practice problems for first mid-term. Solutions.

Practice problems for second mid-term and solutions.

A useful reference for branch cuts . Also useful might be this video from 29 minutes on to roughly 39 minutes. But beware that the rest of the video talks about Riemann surfaces etc. which is beyond our syllabus. But in those minutes the lecturer talks about branch cuts for (z-a)^{1/2}(z-b)^{1/2}, a special case of which was covered very hurriedly in class today.

Practice problems for the final and solutions.
