在高中数学里面，我们学习了一些基本初等函数的导数，根据基长初等函数的导数，以及复合函数的求导法则解决了一些其他函数的求导问题，并且利用函数的导数解决了一些单调问题、极值问题等等．我们只是知道了这些基本初等函数的导数形式，那么我们如何立足高中数学去求解这些基本初等函数的导数呢？如果我们不利用计算机辅助，我们能否从函数求导的基本定义出发去求解出这些基本初等函数的导数呢？事实上是可以的，下面我们来具体说明论证.

In high school mathematics, we learn some of the basic elementary function of the derivative, according to the basic elementary functions derivative, as well as composite function requirements guide rule to solve the some of the other functions of the derivative problem, and the use of the function of the derivatives to solve the some monotonous problemextremal problem. We just know that the derivative forms of these basicelementary functions, how we based high school math to solve these basic elementary functions derivative? If we do not take advantage of the compoter-aided, whether we can fr...
