导数是高中数学研究函数的重要工具,也是学习高等数学的基础.导数的几何意义是导数的重要考点之一,在历年数学高考中经常和其他知识综合在一起进行考查.把握导数几何意义的常用类型问题,对于学生学好导数有着极其重要的意义.笔者根据高三教学经历将切线问题总结如下.
Derivatives is an important tool for high school mathematics research function, but also is the basis for learning higher mathematics.Duegeological meaning of derivatives is one of the important test points of derivative, in the mathematics college entrance examination over the years often combined with other knowledge to examine.Get the general meaning of derivative geometry Type problems, for students to learn a good derivative is extremely important.The author according to the teaching experience of the tangential problem will be summarized as follows.
