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.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

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.
