用导数求曲线的切线方程,是高中数学教学的重要内容,也是高考重点考查的知识点之一。由于导数是新增内容,曲线的函数大多为高次函数,学生不熟悉方程的曲线。因而在解题中常出现疏漏和错解。针对用导数求切线方程的几种常见题型,进行归类分析,以便对学生的学习有所帮助。 Using the derivative of the tangent curve of the curve, is an important part of high school mathematics teaching, but also one of the key points of the exam. Since the derivative is new, most of the curve functions are higher-order functions, and students are not familiar with the equation curve. Therefore often appear omissions and misunderstandings in solving problems. For the tangent equation with the derivative of several common questions, the classification analysis, in order to help students learn.
