Text: Walter Rudin, Principles of mathematical analysis, (any edition)

Suplementary reading: Charles Pugh, Real mathematical analysis.

Grade Distribution

Homeworks - 20%, Midterms - 40%, 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 two midterms of 40 points each and a final exam of 80 points. There will be no make-up exams. The midterm score will be calculated by the formula -

MT score = MT1 + MT2 + F/2 - min(MT1,MT2,F/2).
To pass the class, you have to take the final exam.

Special Announcements

If you are a student with disability (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 04th.

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 04th.

Writing Proofs

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.
