    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.

    To that end, let + be any prime larger than and | |. We know from the above that ( k + 1 ) ! {\displaystyle (k+1)!} divides each of c a ∫ 0 ∞ f k ( t + a ) e − t d t {\displaystyle \textstyle c_{a}\int _{0}^{\infty }f_{k}(t+a)e^{-t}\,\mathrm {d} t} for 1 ⩽ a ⩽ n {\displaystyle 1\leqslant a\leqslant n} , so in particular all of those ...

  8. Irrational number - Wikipedia

    en.wikipedia.org/wiki/Irrational_number

    For example, consider a line segment: this segment can be split in half, that half split in half, the half of the half in half, and so on. This process can continue infinitely, for there is always another half to be split. The more times the segment is halved, the closer the unit of measure comes to zero, but it never reaches exactly zero.

  9. Six nines in pi - Wikipedia

    en.wikipedia.org/wiki/Six_nines_in_pi

    A sequence of six consecutive nines occurs in the decimal representation of the number pi (π), starting at the 762nd decimal place. [1] [2] It has become famous because of the mathematical coincidence, and because of the idea that one could memorize the digits of π up to that point, and then suggest that π is rational.
