MT: We appreciate that “tangent lines” is defined in the glossary, but think “instantaneous speed” and “differential calculus” should also be defined.YB: We will do this!

MT: On page 40, “integral calculus” needs to be defined in the glossary, especially because this chapter dumps a lot of new terms on students, and therefore as much clarity as possible is a must.YB: Yes, we will do this.

PH: Fundamental Theorem of Calculus: The First Fundamental Theorem F(b) – F(a) instead of f(b) – f(a).YB: Good catch, we will fix!

PH: Pythagorean Theorem: Pythagorean instead of PythogoreanYB: Good catch, we will fix!

DM: The Pythagorean Theorem glossary entry: if you are willing to include a small drawing in your glossary, the Pythagorean proof is very simple and intuitive. See “Pythagoras’ Proof” here. As a side note, I went to one of Edward Tufte’s presentations yesterday where he mentioned never having seen a good Pythagorean Theorem visual proof. I sketched that one down on the back of my business card, not knowing that it was the one due to Pythagoras, and gave it to him after the lecture. When I read your book today, I thought of the same proof and thought “maybe they link to it on Wikipedia” and discovered that it is in fact Pythagoras’ own proof. I found it, not attributed to Pythagoras, probably while a senior in college, and was blown away that it was so simple and intuitive and that nobody in any math class had ever put it on the board.

YB: For slope, add “rise over run”. For tangent line, cover kissing and surfing.
