In mathematics, the Leibniz formula for π, named after Gottfried Wilhelm Leibniz, states that 9 ⋯ {\displaystyle {\frac {\pi } {4}}=1- {\frac {1} {3}}+ {\frac {1} {5}}- {\frac {1} {7}}+ {\frac {1} {9}}-\cdots =\sum _ {k=0}^ {\infty } {\frac { (-1)^ {k}} {2k+1}},} an alternating series.

2020年3月6日 · 按照下图的 算法，似乎可以算出圆周率 π π 等于4： 这个结论肯定是错误的，这篇文章就来仔细解释下。 1 周长和面积. 确实，随着不断弯折，圆外多边形看上去越来越接近圆： 那为什么文章开头的结论是错误的呢？ 我们需要明白，在这个弯折过程中，圆外多边形的周长和面积发生了不同的改变： 1.1 周长不变. 将圆的右上角放大，可见外接正方形的边无论折成多少个阶梯，只要恰当地平移这些阶梯，就可以还原出之前的正方形（动图出处）： 也就是说，在弯 …
