Trigonometric Identities

I have a much younger sister who is currently in high school. In her mathematics classes, she has started to get into trigonometry and trigonometric identities. A few nights ago, she had some questions, which got me thinking once again about how mathematics is taught.

The Great Gatsby

This morning, a comic by Zach Weiner:

Saturday Morning Breakfast Cereal

Saturday Morning Breakfast Cereal is a great comic, even if it does veer off into not-safe-for-work territory from time to time. You should all be reading it.

What Math?

As should be clear by now, I love mathematics. I like working through problems, and I enjoy the insights that can come from a good understanding of mathematical logic. Moreover, I strongly believe that mathematics is essential to a strong liberal arts education.

Unfortunately, many people seem to disagree with me. They think that mathematics is a bunch of recipes for finding the solutions to problems, and that it has no place in a liberal education. Only nerds would ever want to study mathematics.

Thus it is nice when I see articles like Dr. Robert Lewis’ What Math? His diagnosis is, I think, spot on. In short, he believes that most people have a misconception about what mathematics is and how it works. The article is short and insightful, and well worth reading.

This happens in part because state certification agencies do not require such experience, and teacher education programs are designed to meet state standards.
