There used to be an entry here that the trigonometric functions for angles => 90° had not been dealt with. I am putting this reminder here. That surely comes before trig identitites. RoseParks
I removed it because the unit circle section takes care of all angles. The section and graphic could use refinement, but that's what the wikipedia is for :).---- I see box for a graphic of a unit circle, but no graphic? Anyone else see it?? RoseParks
I'm trying to send the gif, but the guy I'm supposed to email it to is having trouble recieving it. I'm going to refine the graphic and try again later.
