Things I Taught Today

1. The integral test. Students were miffed that I expected them to be able to integrate simple expressions quickly without seeing all the steps.


2. The Golden Ratio and the Golden Rectangle. And how most of the hype about it is bunk (pdf). Students weren't sure who to believe: me or the textbook.


3. How to prove the division algorithm using strong induction. Not my students. Not sure what they thought.
