自然指数函数展开式的多重分割法(五)──应用部分

The Method of Multi-Separable Expansions for the Expansion of Exponential Function (Ⅴ)──Application

以自然对数函数展开式的多重分割法作为抽象双曲函数的应用．在计算过程中出现对数函数与反正切函数的关系式（这一结果与著名的Euir公式遥相呼应），它在有理函数积分中获得应用．

In this Paper, the author applies the method of multi- separable of the logarithmicfunction to the abstract hyperbolic function. In the calculating, it is found that the relationship betweenlogarithmic function and are - tangent function corresponds to the well known Euler formula. This can beapplied in the integral of rational function
