运用极限解析高考压轴题

Applying Limit Analysis to College Entrance Examination Questions

近年来全国许多省市的高考数学试卷,皆出现了以大学高等数学为背景的命题形式,其中全国卷压轴题出题方向趋向于关于函数导数运用以及零点求取,该类题目运用高中知识范围内的思路与步骤求解相对复杂。本文通过对2016年全国卷理科试题中原题的讨论分析,探究在函数零点求取的问题中解答步骤与思路简便化。利用极限和导数相结合能较好处理高考压轴题,是一种可以借鉴的方法。

College entrance examination mathematics examination in many provinces and cities across the country in recent years,there appeared to the University of higher mathematics as the background of the propositional form,including the volume finale Title questions tend to a derivative of the function and use of zero point finding,this kind of problem by thinking and solving steps of knowledge in high school is relatively complex.In this paper,through the analysis and Discussion on 2016 the volume of science questions central questions,answer the inquiry steps and ideas in simple function zero seeking question.Using the limit and derivative combination can better deal with the college entrance examination finale title,is a method that can be used for reference.
