    Here is a simple way to prove that \( \pi \) is irrational using simple techniques of integral calculus. Who want's to try it on the occasion of \( \pi \) day

    try to prove it's irrationality. not difficult if you follow the instructions given above image.

    Nope ... that does not prove pi is irrational.

    it's the fundamental misunderstanding between limit and value of function. If you find limit of a function, it does not necessarily say that the function has that value.

    Pi is irrational because it never ends or repeats, right?

    That can be found here : http://en.wikipedia.org/wiki/Proof_that_%CF%80_is_irrational I can not type the whole here.. It is too long!

    yes the proof of irrationality of pi is not simple. I found particularly this one understandable http://en.wikipedia.org/wiki/Proof_that_%CF%80_is_irrational#Niven.27s_proof
