摘要
幂指函数的求导在一元函数的学习过程中是个难点,介绍了易于理解和计算的辅助函数求导法,并利用导数的定义给出了证明。
To get the derivation of power-exponential function is a problem in the process of studying monadic function. This paper proposes a new method that is helpful to understand and to calculate, and has also given the proof of using the derivative definition.
