First, it is always possible to apply a half-angle formula and find an e 圆周率 圆周率是数学常数,等于任何圆的周长和其直径的比,一个常见的近似值等于3.14159265,常用符号π表示。 π是无理数,不能用分数表示出来(即它的小数部分是无限不循环小数),但近似22/7等有理数。学界认为π的数字序列在统计上是...

This definition of π implicitly makes use of flat (Euclidean) geometry; although the notion of a circle can be extended to any curve (non-Euclidean) geometry, these new circles will no longer satisfy the formula textstylepi=fracCd. Here, the circumference of a circle is the arc length ...
