# Math 15900, Section 43, Autumn 2015

This is a one-quarter long introduction to mathematical proof, analysis, and linear algebra. It is aimed at preparing students for more advanced analysis and algebra courses such as Math 20300.

**Instructor:** Jack Shotton, Eckhart 333, [email protected].

**Text:** Paul Sally, Tools of the Trade, ISBN 978-0-8218-4634-6. In particular, sections 1.1-1.7, 3.1, 3.2, 3.4, 3.6 and 2.1-2.4.

**Lectures:** MWF 11:30-12:20, Eckhart 202.

**Problem sessions:** Mondays 18:00-19:00, Eckhart 207.

**Office hours:** Tuesday 17:00-18:00, Wednesday 17:00-18:00, or by appointment (preferred).

**Important dates:**

- Final exam: Friday 11th December, 10:30-12:30.
- Hour test 1: Wednesday 21st October
- Hour test 2: Wednesday 18th November

**General policy:** There will be two in-class hour tests and a final exam, as well as weekly homework. You should feel free (encouraged!) to work on homework together, but writeups must be independent. The material for the hour-tests will be theorems, definitions and proofs that I did in class, together with questions on the homework sheets. For the determination of the final grade, the weighting will be: 50% on the final, 20% on each hour test, and 10% on the homework.

It is the policy of the Department of Mathematics that the following rules apply to final exams in all undergraduate mathematics courses:

- The final exam must occur at the time and place designated on the College Final Exam Schedule. In particular, no final examinations may be given during the tenth week of the quarter, except in the case of graduating seniors.
- Instructors are not permitted to excuse students from the scheduled time of the final exam except in the case of an incomplete.

**Homework:**This will be posted on here weekly, and due each Wednesday at 1pm in the pigeonhole in Eckhart basement (or in class).

## Resources

Notes, with thanks to Adel Rahman for allowing me to post them here.

Axioms for number systems.

Some of the “further reading” on Gowers’s website might be enlightening.

This book appears to be a nice introduction to mathematical proofs.
