通过分析历届各省市高考数学试题,了解到函数是一个很重要且考察分值多,试题灵活、能力要求更强,而函数的单调性又是函数性质很重要的一个。通过自己几年来的教学以及与同事之间的相互学习中了解。对于函数单调性的学习,学生常常会遇到很多问题,现在就以所了解、掌握到的一些关于函数单调性的内容整理出来,希望帮助学生提高解题能力、增进思维。 Through the analysis of previous provincial math entrance exam questions, we know that the function is a very important and exam points, flexible questions, ability requirements, and the monotonicity of the function is a function of the nature of a very important one. Learn through years of teaching and mutual learning with colleagues. Students often encounter many problems in the study of monotonicity of functions, and now they have learned and mastered the monotonicity of functions. They hope to help students improve their ability to solve problems and improve their thinking.
