Another Proof on the Convergence and Divergence Characteristic of the Binomial Series at the Place of ±1

The proof on the convergence and divergence characteristic of the binomial series at the place ±1 is presented by using J. L. Raabe distinguish method, Leibniz distinguish method, Cauchy convergence principle and a special limit. It is different from other way in its clear train of thought and its easy understanding.
