Definition from Wiktionary, the free dictionary
I'm confused. The greek letter given in the following line from this page:
(geometry) Curved in two directions, like the letter “S”, or the Greek “ς” (sigma).
looks more like a zeta to me. Can someone clarify?
- Um.. zeta is ζ. ς is a sigma (specifically, the final sigma). —Muke Tever 22:21, 13 July 2006 (UTC)
