21 Both products you mention are infinite. In particular, this holds true for the Wallis product. If π π were rational, then it would have a representation as a (finite) fraction. You would not be able to compare the numerator/denominator to the Wallis product, which would only work if the latter terminated after a finite number of terms.
A Major Proof Shows How to Approximate Numbers Like Pi WIRED
Proof that Pi is Irrational Suppose π = a / b. Define f ( x) = x n ( a − b x) n n! and F ( x) = f ( x) − f ( 2) ( x) + f ( 4) ( x) −. + ( − 1) n f ( 2 n) ( x) for every positive integer n. First note that f ( x) and its derivatives f ( i) ( x) have integral values for x = 0, and also for x = π = a / b since f ( x) = f ( a / b − x). We have

[Solved] Lambert's Original Proof that \pi is 9to5Science
Irrational numbers are, by definition, real numbers that cannot be constructed from fractions (or ratios) of integers. Numbers such as 1/2, 3/5, and 7/4 are called rationals.Like all other numbers, irrationals can be represented using decimals. However, in contrast with the other subsets of the real numbers (shown in Fig. 1), the decimal expansion of the irrationals never terminates, nor, like.

A SIMPLE PROOF THAT π IS IRRATIONAL
Theorem Pi ( π) is irrational . Proof 1 Aiming for a contradiction, suppose π is rational . Then from Existence of Canonical Form of Rational Number : ∃a ∈ Z, b ∈ Z > 0: π = a b Let n ∈ Z > 0 . We define the polynomial function : ∀x ∈ R: f(x) = xn(a − bx)n n! We differentiate this 2n times, and then we build:

Shortest (4 mins) proof that pi is an irrational number YouTube
A detailed proof of the irrationality of π The proof is due to Ivan Niven (1947) and essential to the proof are Lemmas 2 and 3 due to Charles Hermite (1800's). First let us introduce some definitions. ∞ X wn Definition. Let w ∈ C. Then we define ew = which converges for all w ∈ C. n! n=0 Definition.
Proof that Pi is Irrational Classic Round Sticker Zazzle
The idea of the proof is to argue by contradiction. This is also the principle behind the simpler proof that the number p 2 is irrational. However, there is an essential di erence between proofs that p 2 is irrational and proofs that ˇis irrational. One can prove p 2 is irrational using only algebraic manipulations with a hypothetical rational.

This contradiction shows that π π must be irrational. THEOREM: π π is irrational. Proof: For each positive integer b b and non-negative integer n n, define An(b)= bn∫ π 0 xn(π-x)nsin(x) n! dx. A n ( b) = b n ∫ 0 π x n ( π - x) n sin ( x) n! d x. Note that the integrand function of An(b) A n ( b) is zero at x= 0 x = 0 and x=π x.
