basic elementary functions are continuous on their domain 基本初等函數(shù)在它們的定義域內(nèi)都是連續(xù)的。
this paper, using the method of differential equation, proves some characters properties of basic elementary function, and then concludes an equivalent representation about basic elementary function 摘要運(yùn)用微積分的方法,對(duì)基本初等函數(shù)的若干特征性質(zhì)進(jìn)行了證明,從而給出了基本初等函數(shù)的等價(jià)表征。

proving lagrange theorem mean through the introduction of auxiliary function, this article puts forword the methods of building auxiliary function by the mathematical operations and two functions compound operation; this is a method building all elementary function by the basic elementary function, which is a way to solve the problem of the auxiliary function building 摘要文章給出了用四則運(yùn)算以及兩個(gè)函數(shù)的復(fù)合運(yùn)算構(gòu)造輔助函數(shù)來證明拉格朗日中值定理的方法,這也是用基本初等函數(shù)構(gòu)造全部初等函數(shù)的方法,因而比較圓滿地解決了輔助函數(shù)構(gòu)造問題。
