摘要
证明了实对数导数在实数域内处理函数积、商、幂、方根及复合函数的计算公式 ,并把这些定理和公式应用到简化求导运算。
In this paper, the formulas of real logarithmic derivative are proved in solving product, quotient, power, radical and composition of functions in the real domain. The theorems and formulas are applied in simply finding derivative, error estimate and economic elastic analysis.
