Key2Pay “PI”
I have been fascinated by mathematics since childhood, so Pi is one of the most exciting numbers I love. 540 numbers after 3 have been calculated and built into this fascinating contactless payment device.
Below are 2 descriptions about PI. Have fun with it – LAKS😊
Almost simple:
PI, the Greek letter for p, or π, is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the size of the circle, this ratio is always equal to pi. In decimal form, the value of pi is approximately 3.14.
Deeply technical:
The circle number (pi), also Ludolph’s number, Ludolf’s number or Archimedes’ constant, is a mathematical constant that gives the ratio of the circumference of a circle to its diameter.
This ratio is the same for all circles, regardless of their size.
The circle number is a transcendental and therefore also irrational number.
Its decimal fraction begins with {\displaystyle \pi =3{,}1415926\ldots }{\displaystyle \pi =3{,}1415926\ldots }, although in practice often only three significant digits are used: {\displaystyle \pi \approx 3{,}14}\pi \approx 3{,}14.[A 1]
The circle number not only occurs in geometry, but also has significance in other mathematical subfields and theories. For example, it can be used to connect the solution of the classical Basel problem with the theory of Fourier series.
