在高中数学里,常常需要通过构造函数解决问题,这种方法一般都没有系统地加以训练,而是散布在解题的过程中.老师在讲解的时候经常是直接给出了函数,并没有说明为什么,学生往往感觉到结论来得很突然,对这种方法觉得难以掌握.那么在具体运用这种方法时该如何去分析、发现、构造出 In high school mathematics, often need to solve the problem through the constructor, this method is generally not systematically trained, but scattered throughout the process of solving problems. Teachers often give a direct explanation of the function, did not explain Why, students tend to feel the conclusion is very sudden, this method is difficult to grasp. So in the concrete use of this method, how to analyze, discover, construct
