you know, I actually understood that, in general.
that's actually amazing since i'm miserable at math. ---

Originally by: DuffmanPeter Also if you think math is hard, try real variables or abstract algebra. Then you can bang you head against the wall like I am almost lol.
I bang my head on the wall with 11th grade math.
that's just how bad I am at it. I probably need a math course ground up from the 9th grade and up or smth so that I can understand the damn thing. ---

Originally by: Scorpyn Some of the formulas do get simpler, but tbh I don't really see the point in using TAU (2*PI) instead of just PI.
think the problem here is, why using 2Pi for a single unit?
it's a matter of keeping things tidy and clean. ---

Defining TAU as 2*PI would simplify some formulas, while complicating others.
http://en.wikipedia.org/wiki/Pi
Personally I'd rather multiply by 2 than divide by 2.
Also, if you don't understand PI, you won't understand 2 * PI.
Edit : If you don't like 2 * PI, then instead of 2 * PI * r, simply use PI * d.
well yeah. Still, for operations where you use a full circle instead half, Tau is better, for everything else, Pi? ---

You have a circle.
What is easier to measure? The diameter or the radius? In most cases, it's the diameter.
PI is based on the diameter. This simplifies some formulas, because you can re-write them to use the radius instead of the diameter when you need half the diameter.
Of course, you can use the radius instead of the diameter, just use 2r instead. However, using that as a justification to define TAU as 2PI is just silly.
then I ask for forgiveness about my crass mistakes.
I'm as dumb as a door when it comes to maths, and apparently more dumber than I thought. ---
