| Abstract: | According to a known series, by splitting terms, the reciprocals series alternated with positive and nega- tive of binominal coefficients is obtained. And by complex function, the closed formal is obtained. The closed form of sum of the dual trigonometric function series alternated with positive and negative, whose coefficients involving reciprocals of binominal coefficients, is given. |
