二项式级数在±1处敛散性的证明

The Proof of the Convergence and Divergence Character of the Binomial Progression Series at the Place of ± 1

借用拉阿伯判别法、莱布尼兹判别法、高斯判别法、柯西收敛准则，以及一个特殊极限，给出了二项式级数在±1处敛散性的证明。

The writer proves the convergence and divergence character of the binomial progressionseries at foe place of ± 1 by using J. L. Raabe distinguish method, Leibniz distinguish method, Gauss distinguish method, Cauchy convergence principle and a special limit.
