2014年各省市高考导数综合题大都将导数内容和不等式、函数与方程等有机结合在一起考查。这些题目很好地贯彻了《考试说明》中“鼓励考生多角度、创造性地思考和解决问题”的高考命题依据。现结合2014年部分高考题,对构造函数谈几点感想。1.对研究目标移项作差或去分母变形构造函数,实现函数灵活转化导数综合题有的以函数的形式给出,这种形式往往对函数直接求导,求函数的最值即可。但导数综合题更多
Most provinces and cities in 2014 entrance exam synthesizer questions most of the derivative content and inequality, functions and equations and other organic combination of examination. These topics well implement the “test description” “encourage candidates to multi-angle, creative thinking and problem solving ” college entrance examination proposition basis. Now combined with 2014 part of the college entrance examination, on the constructor to talk a few thoughts. 1. Research on the target shift or denominator deformation of the constructor to achieve flexible function conversion Derivative synthesis some of the questions given in the form of a function, this form is often direct derivative of the function, seeking the value of the function can be. But the derivative synthesis problem more
