Some Trig
A large portion of the “standard” precalculus curriculum consists of a rather tedious recitation of trigonometric identities. I am largely of the opinion that there are only a couple that one really needs to know—for example, the Pythagorean identity (\(\sin(\theta)^2 … Continue reading
Calculus I—Days 23 & 24
The term is rapidly drawing to a close, and I am beginning to feel just a little overwhelmed. Moreover, the class has finally hit a rhythm, and the things are mostly running smoothly, thus I have less to discuss in … Continue reading

On an utterly unrelated note: my family and I moved to a different house last summer. Because we have somewhat less space than we did before (much larger yard, but about 200 square feet less living space), we have been … Continue reading
Calculus I—Day 14
After three weeks of instruction, we finally got to our first applications (i.e. “story problems”): exponential growth and decay models. As the problems themselves can be solved in terms of algebra techniques applied to exponential functions, it seems odd to … Continue reading
