学了李向忠、张钟谊二位老师在《中学生数学》2003年11月期上发表的“绝对值几何意义的应用”一文后,同学们可能会对二位老师的“提示”:“应用绝对值的几何意义去解绝对值的一些题目,能使解题过程大为简化和直观”产生共鸣,有所感悟.那么,你对二位老师的“告诫”:“当绝对值的个数多于两个,或者当x的系数不是1时,就无法利用几何意义”求解有何认识,有无困惑?你会对此提出质疑吗?你会探究进而释疑吗?
After learning the article “Application of Absolute Geometric Meaning” published by the two teachers of Li Xiangzhong and Zhang Zhongyi in “Middle School Mathematics” in November 2003, the students may “prompt” two teachers: “Absolute value is applied. The geometric meaning to solve some of the absolute value of the problem, can make the problem-solving process greatly simplified and intuitive ”resonance, some understanding. Then, your “admonishment” to the two teachers: “When the absolute number of more than two One, or when the coefficient of x is not 1, it is impossible to make use of the geometric meaning ”what understanding does the solver have and whether it is puzzled? Would you question this? Do you explore and question it?
