Mathematics Constants ~ Mathematical Formula Table and List

A mathematical constant is a quantity, usually a real number or a complex number, that arises naturally in mathematics and does not change. Unlike physical constants, mathematical constants are defined independently of any physical measurement
there is some of Mathematics Constants

Phi

Definition :
The constant p (Greek letter pi) is, classically, defined as the ratio of the circumference p of a circle to its diameter d:
p = pd = 2pr
and, as proved by Archimedes of Syracuse (287-212 BC) in his famous Measurement of a Circle, the same constant is also the ratio of the area A enclosed by the circle to the square of its radius r:
A = pr2.

or phi = 3.14159265358979323846264338327950288419716939937510

E Constans

This limit is well defined and it was denoted by the letter e by the Swiss mathematician Leonhard Euler (1707-1783), first around the end of year 1727 in a manuscript entitled Meditatio in Experimenta explosione tormentorum nuper instituta (Meditation upon experiments made recently on the firing of Canon)
