YAY! No more impossible trigonometric equations for me!

sounds very interesting... I'm gonna look into that, i think... haven't finished reading the first chapter yet, but I'll write something when i have

Wish I could've had this 4 years ago.

I'm going to print chapter one out and read it too.

I am wondering if the new methods will help simplifiy some of the bot programming we're doing.

Trig was actually easy for me. It does make sense to use length squared, though, then use square root at the end.

Zacker, both links work. For the Chapter 1 link, you need a PDF reader such as Adobe Acrobat.

Well I've read the basic theory now... and i must say i can see the point in this...

The basic calculations do become a little harder to do, i think... but it is so much more straightforward and logical... i mean, it's pretty logical that a 45degree angle has a spread of 1/2 instead of 45... 45 only makes sense in a 60digit number system (i don't know the word but i hope you know what i mean)

So alltogether I think this is very neat. It doesn't revolutionize anything though... cause you still have this weird 'spread' thing to deal with, instead of angles, and while the spread thing can be calculated pretty straightforward, it's still a fairly confusing thing before you get used to it... so to say this will make trigonometry a lot easier would be a lie...
