Quandaries
and Queries
To whom it may concern:
I am a student in the 10th grade and attending advanced math at my high school. I was assign to do a report about the unit circle and the radian. But there seems to be no information available about the history of the radian; who first found out about them, which civilizations used it if any. Well, hopefully you'll assist me in this troubling question. Thank you for your kind consideration.

Hi Erikson,
The place where I look for the history of mathematical terms is Earliest Known Uses of Some of the Words of Mathematics. If you go there and look under the letter R, the first entry is on radians.
I hope this helps,Penny
