数学思想方法在求参数取值范围中的应用

Applications of Mathematical Thought Method in the Range of Numerical Value in Extraction of Parameter

在全面实施素质教育的今天 ,数学思想方法的培养在中学尤为重要 在求参数取值范围时可以应用函数与方程的思想方法、数形结合的思想方法。

Nowadays,mathematical thought training plays on most important role in all-round quality education in middle school.This paper will discuss applications of mathematical thought method in the range of numerical value in extraction of parameter from the following questions one by one:function and equation;combination of number and picture;classified discussion and simplification.
