Question

prove that pi is an irrational number.

Answer 1

This is well above my mathematical pay grade, but if you are truly interested there is a good wikipedia article on the subject...

Answer 2

yes, i am reading it right now. it is just my first question, so i wanted to try one that is easy to ask and hard to answer. :) by the way, i hardly can understand the proofs!

Answer 3

pi is also transcedental, meaning it cannot be the solution of any equation with rational coefficients.

Answer 4

just put all of the numbers after the dot, and people know it is irrational.
