Abstract

Summary We establish the convergence of a family of series for which the usual convergence tests fail. In addition, we show how to use elementary methods to find the sums of the series. A wealth of problems for both calculus students and real analysis students can be obtained from this collection of series and connections can be made to both differential equations and hypergeometric functions.

一些令人惊讶的级数和
我们建立了一类级数的收敛性,而通常的收敛性检验对它是无效的。此外,我们还展示了如何使用初等方法求级数的和。对于微积分学生和实分析学生来说,从这个级数集合中可以得到大量的问题,并且可以将微分方程和超几何函数联系起来。
