Mathematicians say pi is the wrong figure to de associated with propertes of circle. Tau, which is 2pi(6.28) is the natural measure, they say.

who said anything about wrong...it says tau is 2 x pi ...think before u postMeaning that we are using the wrong number to solve for all unknown lengths.... so it is a big difference.
Really, that's nothing. It's simply someone trying to shorten down the formula.
2πr = C
Pi is in fact the proper value to associate, as it is the ration of the circumference of the circle to its diameter, and this works for all circles, period.
A "tau" as you call it, would mainly simplify that one formula, where as we still have other formuli that pi works quite well for, such as πr^2 (Area of a Circle) or (4/3)π^3 (volume of a sphere).
No, it would make it far more complicated.Ooooh so they're trying to make it easier is that what you're saying? So instead of it being like 2PixR it would just be TauxR
I'm probably wrong I suck at understanding math. If that is right then I'm happy XD
Ok I see know sorry for being so dense. Thanks for explaining. I'm back to my original stance on it lol.No, it would make it far more complicated.
The formula for circumference is 2πr = C, where C is circumference and r is radius. If you divide π you get 2r = C/π, or Diameter equals circumference divide by pi, thus pi being the ratio of circumference to diameter.
Using tau would shorten only the one formula to tau*r. Why not just write the formula πd, where D is diameter? (Diameter is 2r).
Many formula would have to be rewritten to a form to integrate tau, which not only makes them for difficult than the older formula, they are no more correct.
Example: πr^2 (Area of a Circle) would now have to be written as: 1/2(tau)r^2, or simplified down to: "tau r squared, over two." The original pi r squared formula is better.
