高中教材引进导数之后,无疑为函数的研究与应用提供了一种有效的工具,把初等函数的学习提高到了一个新的层次.正因为如此,近年来,对应用导数研究函数性质的考查,已成为高考的热点和重点.对导数应用方面的指导与考查,主要体现在如下几个方面:求切线方程,研究函数的单调性,求函数的极值、最值或值域,确定使 Introduced derivative of high school teaching materials, undoubtedly provides an effective tool for the study and application of functions, which takes the learning of elementary functions to a new level. Because of this, in recent years, the study on the properties of applied derivative research functions Become the hot spot and focus of the entrance examinations.The guidance and examination on the application of the derivation are mainly reflected in the following aspects: finding the tangent equation, studying the monotonicity of the function, finding the extremum, the most value or the range of the function,
