函数内容历来是高考命题的重点,在试题中所占比重最大。由于函数问题的综合性较强、知识点零碎、题型较多,因此学生在解答此类问题时常常会感到力不从心。导数作为高中数学新的知识点,不仅是我们要掌握好的重要学习内容,也是解决函数问题的好方法,下面我们举例说明如何利用导数解答函数问题。一、利用导数求函数的单调区间单调区间作为函数的重要性质之一,在高考中会被重点考查。传统求单调区间的方 Function content has always been the focus of college entrance examination proposition, the largest share of the questions. Due to the comprehensiveness of the functional problems, fragmented knowledge points and more types of questions, students often find themselves unable to answer such questions. Derivatives as a new high school mathematics knowledge point, not only we have to master a good important learning content, but also a good way to solve the function of the problem, below we give an example of how to use the derivative function to answer the question. First, the use of derivatives of the monotonous interval function Monotone interval as one of the important properties of the function, in the college entrance examination will be the focus of examination. Tradition for the monotony of the square
