Re: Happy Pi Day!

I like the constant 3 + (1/5) much better.


In mathematics, you don't understand things. You just get used to them.

If it ain't broke, fix it until it is.

it isn't. however, my maths teacher's birthday is on pi day, so i must remove her bragging rights somehow. joking aside, i believe that we should us tau for angles and pi for areas.

Tau is the name given to a constant which is twice pi, I think.

Re: Happy Pi Day!

(I am amazed that list of useful symbols at the top of the page doesn't include pi!)

tau = 2 pi, the measure of a full circle. There are those who argue that tau would be a better choice than pi, but I haven't found that their arguments hold much water. For every calculation it simplifies, it makes another more complex.

exactly! hence my suggestion of a dual system, or at least using tau for angles.
