Abstract
We present a procedure and a MATHEMATICA code for the conversion of formulae expressed in terms of the trigonometric functions sin (ω x), cos (ω x) or hyperbolic functions sinh (λ x), cosh (λ x) to forms expressed in terms of η_m(Z) functions. The possibility of such a conversion is important in the evaluation of the coefficients of the approximation rules derived in the frame of the exponential fitting. The converted expressions allow, among others, a full elimination of the 0/0 undetermin...

本论文提出了一种将涉及正弦函数sin(ωx)、余弦函数cos(ωx)或双曲函数sinh(λx)、双曲余弦函数cosh(λx)表达的公式转换为以η_m(Z)函数形式表达的方法及其MATHEMATICA代码。此类转换在评估基于指数拟合框架推导出的近似规则系数时具有重要意义。转换后的表达式能够实现诸多功能，其中之一即为完全消除在指数拟合框架下推导出的近似规则系数中的0/0不定性。
