对数学思想的灵活应用,是数学学习走向更深层次的一个标志.它能指导我们有效地应用数学知识探索解题方向.含绝对值不等式的解法是高一数学中很重要的内容,也是学生感到难学的一部分内容.解绝对值不等式的基本数学思想是将含绝对值的不等式同解变形为不含绝对值的不等式,用到的
The flexible application of mathematics thinking is a sign of a deeper level of mathematics learning. It can guide us to effectively apply mathematics knowledge to explore the problem-solving direction. The solution with absolute value inequality is a very important content in high school mathematics, and it is also felt by students. Part of the difficulty of learning. The basic mathematical idea of solving the absolute value inequality is to transform the solution containing the absolute value inequality into an inequality with no absolute value.
