wut?

zzr0ck3r · Answer

There is no way to write pi in decimal form, or as the ratio of two integers.

triciaal · Answer

usually just use 3.142 when not using 22/7

anonymous · Answer

ok then

zzr0ck3r · Answer

these are all approximations.....make sure you understand that.

zzr0ck3r · Answer

The best way to think about pie, is by taking a circle, and "unrolling it", and out that in a fraction with the circumference|dw:1418186958567:dw|.

zzr0ck3r · Answer

in a fraction with the diameter*

anonymous · Answer

Another way of seeing it is that $2\pi$ is the circumference of a unit circle.

ganeshie8 · Answer

how do you define pi in real numbers @zzr0ck3r 
just curious.. if it is easy to define it using dedekind cut or cauchy sequences.. .

anonymous · Answer

If you want a sequence converging to $\pi$, just take a series expansion of $\pi$ and then expanding up to $n$ terms would be the $n$'th element of the sequence. http://en.wikipedia.org/wiki/Leibniz_formula_for_%CF%80

zzr0ck3r · Answer

no idea @ganeshie8

ganeshie8 · Answer

okay i thought dedekind cuts are part of real analysis defining a cut for irrational numbers like $\sqrt{2}$ etc looks easy but i guess transcendental numbers are tricky http://en.wikipedia.org/wiki/Dedekind_cut
