纵观近几年的各省高考试题,不等式与函数、导数的结合是命题的热点,通常具有一定的难度,作为试卷的压轴题时常出现.这类考题分两个部分.第一部分以函数为载体,导数为工具,考查函数诸多性质和导数极值理论、几何意义,第二部分以不等式问题为呈现形式,多是不等式的证明,对于此类不等式问题,常用方法是通常构造函数法,数学归纳法,但是由于难度大等诸多原因,很难下手,或即使找到突破口,也很难顺利解决,这里给大家介绍利用定积分 Throughout the provincial college entrance examination papers in recent years, inequality and function, the combination of derivatives is the hot topic proposition, usually with a certain degree of difficulty, as a finale of the papers often appear.This type of test questions are divided into two parts.The first part of the function as a carrier , Derivatives as a Tool, Examine Function Many Properties and Derivative Extremum Theory, Geometrical Significance, Part II The Problem of Inequality as a Presence, Mostly a Proof of Inequality, Commonly used methods for such inequalities are the usual constructor method, mathematical induction Act, but because of the difficulty and many other reasons, it is difficult to start, or even find a breakthrough, it is difficult to successfully solve, here to introduce the use of definite integral
