Motivated History of Mathematics - Circles and Tangents

Theron Hitchman shares his thoughts about teaching a course about the history of mathematics. I took that course (the "to the calculus" version, not the "from the calculus" one) as a UNI undergrad and remember the experience well. (Although I've surely forgotten most of the proofs.) In my comment, I discuss the possibility of designing a history of math class to specifically support Freudenthal's principle of "guided reinvention."
