导数是现行高考的必考内容,选择题、填空题、解答题均可出现,且每年必有一道解答题,通常考查实际问题中的最值求法,与单调性有关的参数取值范围及与切线有关的综合题等·本文归类说明导数的重要作用,供同学们参考·一、应用导数定义的等价形式解题例1设函数f(x)在x=a处可导,且f
The derivative is the required content of the current college entrance examination. The multiple-choice questions, blank-fill questions, and answer questions can all appear. There must be one answer question each year. Usually, the most value-finding method in the actual question is examined, and the range and value of the parameters related to monotonicity. The tangent-related comprehensive questions, etc. This article classifies the important role of the derivative for the students to refer to. First, the application of the derivative of the definition of the equivalent form of the solution to the problem Example 1 set function f (x) at x = a derivative, and f
