函数是高中数学的重要内容,是高考命题的热点,大多以压轴题的形式呈现,函数的好多性质直接研究起来往往非常麻烦.而在新课标中将导数作为选修中的必修内容,因而为研究函数提供了一种强有力的工具,除此之外,利用导数还可以对学生进行强有力的理性思维训练.自从导数进入新教材后,给函数的研究注入了勃勃的生机和活力,开辟了许多解题的新思路、新空间、新方法和新途径,同时也拓展了高考对函数问题的命题空间.导数考题分为基础层次和提高层次.基础层次是导数的简单应用,主要包括探求函数的单调 Function is an important part of high school mathematics, is the hot topic of college entrance examination proposition, mostly in the form of finale questions, the nature of the many functions of the direct study is often very troublesome.While in the new course standard derivative as a compulsory content, Research function provides a powerful tool, in addition, the use of derivatives can also be a strong rational thinking training for students since the derivative into the new textbook, the study of the function has injected vitality and vitality, opening up A lot of new ideas, new spaces, new methods and new ways to solve the problem, but also expand the college entrance examination of the problem space for the function of the problem. Derivative test questions are divided into basic level and improve the level of the basic level is the simple application of derivatives, including exploration Monotonous function
