If you’re looking for spaced repetition software, check out Anki. It is a great program.

There are other good programs that do spaced repetition.

The Epsilon-Delta Story and Examples

Posted in 2016 -- MATA31H3F, Lecture Notes, Uncategorized by pgadey on 2016/09/21


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 \lim_{x \rightarrow 3} (2x + 3).

Trigonometry Review

Posted in 2016 -- MATA29H3F, 2016 -- MATA31H3F, Uncategorized by pgadey on 2016/09/15


Some notes that I prepared about trigonometry are available here.

The notes sketch things like y = 2 \sin\left( \frac{1}{3}x \right) + 4 and solve equations like \sqrt{2} \cos( 3\theta) = 1.

The Hardware and Software of Theoretical Machines

(This blog entry is a written summary of an pair of talks given at Canada Math Camp on 2015-07-28 and 2015-07-30. The official notes are on

Computers are all around us. This fact is so self-evident that writing it down, on a computer no less, is slightly embarassing. And yet, very few people ever talk about exactly what a computer is. Whenever it comes up one feels like St. Augustine, who said: “What is a computer? If no one asks me, I know what it is. If I wish to explain it to him who asks, I do not know.”

This talk is an informal introduction to the formalizations of computation adopted by Alonzo Church and Alan Turing, the two Great Definers of Computation. We’ll also say something about Charles Babbage because he too was awesome.
