整体最值法是利用独立参数法解决含参数的导数恒成立问题时,遇到分离参数后的函数的最值不容易算出或者取最值的变量使得分母为零,从而无法求出最值时采用的方法,是不用分离出参数通过求带参数的函数的最值来解决问题的方法.本文将通过几道具体的实例,介绍整体最值法解决含参数的导数恒成立问题的方法及窍门.整体最值法要特别注意对参数的取值范围的讨论,做到不重复,不遗漏,参数的取值范围要将题目中给定的范围都覆
The whole most value method is to use the independent parameter method to solve the problem of the constant containing the parameter. When the value of the function after the separation parameter is encountered is not easy to calculate or take the value of the variable so that the denominator is zero and the maximum value can not be obtained The method is to solve the problem without separating the parameter by finding the value of the function with the parameter.This paper will introduce several methods and tricks to solve the problem of the constant of the derivative with the parameter by several concrete examples . The overall value method should pay special attention to the argument of the range of values to be discussed, so that do not repeat, do not miss, the range of parameters should be covered in the title range
