  2. Proof that π is irrational - Wikipedia

    en.wikipedia.org/wiki/Proof_that_π_is_irrational

    Written in 1873, this proof uses the characterization of as the smallest positive number whose half is a zero of the cosine function and it actually proves that is irrational. [ 3 ] [ 4 ] As in many proofs of irrationality, it is a proof by contradiction .

  3. Pi - Wikipedia

    en.wikipedia.org/wiki/Pi

    The number π (/ p aɪ /; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter.It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of a curve.

  4. Transcendental number - Wikipedia

    en.wikipedia.org/wiki/Transcendental_number

    Hence, the set of real numbers consists of non-overlapping sets of rational, algebraic irrational, and transcendental real numbers. [3] For example, the square root of 2 is an irrational number, but it is not a transcendental number as it is a root of the polynomial equation x 2 − 2 = 0. The golden ratio (denoted or ) is another irrational ...

  5. Irrational number - Wikipedia

    en.wikipedia.org/wiki/Irrational_number

    A stronger result is the following: [31] Every rational number in the interval ((/) /,) can be written either as a a for some irrational number a or as n n for some natural number n. Similarly, [ 31 ] every positive rational number can be written either as a a a {\displaystyle a^{a^{a}}} for some irrational number a or as n n n {\displaystyle n ...

  6. Proof that 22/7 exceeds π - Wikipedia

    en.wikipedia.org/wiki/Proof_that_22/7_exceeds_π

    Proofs of the mathematical result that the rational number ⁠ 22 / 7 ⁠ is greater than π (pi) date back to antiquity. One of these proofs, more recently developed but requiring only elementary techniques from calculus, has attracted attention in modern mathematics due to its mathematical elegance and its connections to the theory of Diophantine approximations.

    Going back to the holiday's roots, the mathematical symbol Pi is the ratio of the circumference of a circle to its diameter. The value of Pi is approximately 3.14, but it has infinite decimal ...

  8. Gelfond's constant - Wikipedia

    en.wikipedia.org/wiki/Gelfond's_constant

    The numbers π and e π are also known to be algebraically independent over the rational numbers, as demonstrated by Yuri Nesterenko. [3] It is not known whether e π is a Liouville number. [ 4 ] The constant was mentioned in Hilbert's seventh problem alongside the Gelfond-Schneider constant 2 √ 2 and the name "Gelfond's constant" stems from ...

  9. These Funny Pi Day Jokes Will Cause Never-Ending Laughter - AOL

    Like your reasoning for eating that extra slice of pie after dinner, the number pi is irrational, approximately equal to 3.14159 (and so on, infinitely). Because the rounded number of pi is 3.14 ...
