笔者在导数一章的教学中,时常碰到学生问到解参数问题,有时问题解决起来很复杂、很麻烦.数形结合思想是高中数学学习的一种重要思想,也是高中生比较难掌握的一种解题思想.有时利用数形结合可使问题简单明了,本文谈谈利用数形结合思想巧解导数中的参数问题,与读者共同探讨. In the teaching of derivative chapter, the author often encounters the students to ask about the problem of parameters, and sometimes the problem is complicated to be solved, which is troublesome.Digital shape combination is an important thought of high school mathematics learning and it is also difficult for senior high school students to grasp Of the problem-solving ideas.Often using the combination of several forms can make the problem simple and clear, this article talk about the use of combination of the number of ideas to solve the problem of derivative parameters, and readers to explore.
