不等式问题一直是高中数学教学的重点和难点之一,学生的思考和求解只停留在模仿层面上,有时教师命题也一样.下面两道习题非常相似,但在解题过程中意外地发现了极大的“不相似”.于是,我们开展了下面的研究.题目1(2015年湖州市模拟试题)已知x,y为 The problem of inequality has always been one of the most important and difficult points in high school mathematics teaching. Students’ thinking and solving are only on the level of imitation, and sometimes the teacher’s proposition is the same. The following two exercises are very similar, but they were accidentally discovered in the process of solving problems Big “not similar ”. So, we carried out the following research.Question 1 (2015 Huzhou simulation test) known x, y is
