Abstract

Let shx and chx be hyperbolic function,simβ, cosβ be trigonometric function,complex number d≠0. The sum power of hyperbolic function and equal ratios sequence product <superscript>n</superscript>Σ<subscript>k=0</subscript> d<superscript>k</superscript>sh<superscript>k</superscript>kz <superscript>n</superscript>Σ<superscript>k=0</superscript> d<superscript>k</superscript> ch'kz hyperbolic function with trigonometric function <superscript>n</superscript>Σ<superscript>k=0</superscript> sh'kxsinkβ, <superscript>n</superscript>Σ<superscript>k=0</superscript> sh'kxcoskβ are discussed, the calculation formulas are given by the method of generating function.
