Epsilon-delta proofs are the cornerstone of rigorous mathematical analysis.
To help you out, I’ve written up some additional notes on this material.
- Examples of epsilon-delta proofs: contains some proofs with epsilons and deltas.
- The Delta-Epsilon Story: This is extra material to illustrate the purpose of epsilon-delta proofs. It’s a fictitious dialogue between Alice and Bob, two students in MAT A31, who disagree about the value of .

This week we had great attendance at office hours. We solved some questions on the white board in my office; the photos are available below the cut.
To make things more convenient:
Office hours are now 11:30-12:30 on Tuesday and Thursday, and 11-1pm on Wednesday.
Some notes that I prepared about trigonometry are available here.
The notes sketch things like and solve equations like .
There is a camera in my office which I use to take photos of the white board. The photos are automatically posted to http://pgadey.ca/office/cam/. If we work on a question during office hours, then it will appear on that page.
