摘要
运用导数的思想来确定满足拉格朗日中值定理的一类函数,通过具体例子说明如何确定这些函数及由函数的n阶导数来判断函数的性质.
We ascertain a kind of function satisfying the Lagrange mean value theoremis by the thought of derivative. We give the concrete examples to show how to ascertain these functions and to judge the function＇s characters by the n-th derivative.
