中职数学教学对含有绝对值不等式的解法与探索

The Solution and Exploration of Absolute Value Inequality in Mathematics Teaching in Secondary Vocational Schools

根据不等式的性质及其相关定理,运用绝对值的几何意义入手,把含有绝对值的不等式转化成为一般的不含有绝对值的不等式。

According to the properties of Inequality and correlation theorem, the Inequality contai- ning absolute value is converted to general Inequality with no absolute value by using the geometric meaning of absolute value, and thus to get the basic ideas and methods of attaining the solution set of In- equality containing one or two absolute values.
