Re: Angle equationI remember my trig using "SOHCAHTOA" (see http://www.mathsisfun.com/sinecosinetangent.html) "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #3 20050724 21:17:40
Re: Angle equationDivide both sides by cosθ: sinθ/cosθ=0.38 Why did the vector cross the road? It wanted to be normal. #4 20050724 21:19:36
Re: Angle equationSNAP "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #5 20050724 21:37:30
Re: Angle equationYou can time how long it takes people to post? Why did the vector cross the road? It wanted to be normal. #6 20050724 22:00:01
Re: Angle equationNo, not really, though that is an interesting idea. It just seemed to me that there were 3 minutes difference between our posts, but I started first, but . . . oh, I don't know!

Re: Angle equationthe 3d .obj reader i have at http://www15.brinkster.com/nitrofurano/sdlbasic/ uses this #9 20050728 19:46:40
Re: Angle equationthe problem starts when (using arcsin, arccos and arctan) you need to know the quadrant for angles larger than 90degrees (afaik)
