Thanks. I thought calculus went as far back as the Egyptians as well. Wasn't trigonometry developed around that time as well?

Yes. Probably any careful study of astronomy is going to get you into trigonometry, and the Epgyptian, Babylonians and others in that area were all interested in astronomy.
As of course was Ptolemy (the Ancient Greek), who really for all intents and purposes invented trigonometry proper.
