And the number comes out to be somewhat ugly. With the replacement for trig it isn't quite as straightforward. The "simple algebra" doesn't quite stay so simple.

I'm not enough of a math geek to understand on a cursory view if this is real or a con job. ----------------------------------------- George W.

So having a way to think about trig that avoids them is useful. But push come to shove, there is inherent complexity that you aren't going to get around.

Trig is based on measurements of the triangle itself: what is the length of each side, what are the angles, etc. This method seems to enable doing formulas directly on the coordinates. I could be mis-reading -- okay, I didn't read the whole thing -- but that's what it looked like. === Purveyor of Doc Hope's [link\|http://DocHope.com\|fresh-baked dog biscuits and pet treats].

How would you like to trigonometry without sin/cos/tan? - (Silverlock) - (24) - Sept. 18, 2005, 09:58:13 AM EDT

That's just wrong. -NT - (bionerd) - (11) - Sept. 18, 2005, 10:31:45 AM EDT

Agreed if does away with Euclid. - (a6l6e6x) - (10) - Sept. 18, 2005, 01:38:03 PM EDT

I'll have to disagree with you on that - (ben_tilly) - (5) - Sept. 19, 2005, 06:35:17 PM EDT

What's your point? - (mmoffitt) - (2) - Sept. 21, 2005, 12:39:10 PM EDT

My point is that... - (ben_tilly) - (1) - Sept. 21, 2005, 02:49:18 PM EDT
