Abstract:
The research on circumference ratio π in the past millennium mainly
focuses on three aspects: (1) finding the true value of π; (2) telling what type of
number π is; (3) expressing π by infinite expansion. This paper studies π from
another perspective and finds the relationship between it and other mathematical
constants.
Mathematician Euler, in 1743, discovered the famous formula betweenπand number
e (the natural base of logarithm), e iπ +1=0, which indicates their relationship with
imaginary numbers. In this paper, the authors find the real relationship between π
and e, though a new constants μ and Euler constantsγ. The real number relationship
can be expressed by a new formula.
千年来对圆周率 π 的研究主要集中在三个方面:(1)求 π 的真值;
(2)π 是什么类型的数;(3)用无穷展开式表示 π。本文从另一个角度研究它,
寻找它和其他数学常数之间的关系式。
数学家欧拉于 1743 年,发现了 π 和数 e(自然对数的底)之间的著名公式
e iπ +1=0,体现了它们和虚数的关系。本文作者通过研究,发现了 π 和 e,与新
常数 μ 以及欧拉常数 γ 之间存在实数关系。
