纵观近几年高考试题,导数问题一直是解答题中的必考知识点。由于此类问题的难度系数比较高、计算比较烦琐,学生在解答该类问题时失分率较高。学生要想提高解答这类题的正确率,一是要对常见的导数问题有很好的认知,二是要对各问题的解法和注意点有着充分的理解和记忆。本文将结合实例,对利用导数解决函数问题进行分析研究。1利用导数求函数的单调性
Throughout the college entrance examination exams in recent years, the derivative problem has always been to answer the questions in the required knowledge points. Due to the difficulty of such problems is relatively high, the calculation is cumbersome, students in the solution of such problems when the high fractional loss rate. Students want to improve the correct rate of answers to such questions, one is to have a good understanding of the common derivative problem, the second is to have a full understanding and memory of the solutions and points of attention. In this paper, we will analyze and study the problem of using derivative to solve the function with examples. 1 Use the derivative to find the monotonicity of the function
