与函数双零点有关的不等式证明题,其类型主要是与双零点的和、积等形式有关.此类不等式常常与有两个零点时参数的取值范围问题相伴随,一般都需先求出两个零点的大致取值范围.这类不等式的设问指向明确,形式和结构相对简洁,但证明综合性强,运算量大,且证明时常常带有一定的技巧性,对学生的数学思维能力和数学思想方法的应用要求高,难度大.近年来,随着对导数在解决函数问题中应用的深入研究,这类不等式证明 The type of inequalities proves to be related to the double zero point of the function is mainly related to the form of sum and product of double zeroes etc. Such inequalities are often accompanied by the problem of the range of the parameters when there are two zeroes, The approximate range of two zero points.The inequality of this kind of inequality points clearly, the form and structure are relatively concise, but it is proved that the inequality is strong, the operation amount is large, and the proof often has a certain skill, Ability and mathematical thinking and application of high requirements and difficult.In recent years, with the derivatives in solving the problem of function in-depth study, such inequalities that
