函数是初中数学重要内容,一次函数和反比例函数是函数学习的基础,而掌握一些数学思想方法可以提高学生学习能力和解决问题能力。本文从数学解题实例出发,阐述了提炼数学思想方法在解决反比例函数与一次函数问题中的应用和重要意义。
Function is an important part of junior high school mathematics. The first-order function and the inverse-proportion function are the basis of function learning. To master some mathematical ideas and methods can improve students’ ability of learning and solving problems. Starting from the example of solving math problems, this paper expounds the application and significance of the method of extracting mathematical ideas in solving the problems of inverse proportion function and linear function.
