构造法,即对于难以解决的数学题目,根据题的条件和结论所含有的特征,性质等,改变思考问题的方向,从全新的角度,新的观点来读懂题目,了解题目,联系知识点,进而对条件和结论之间,构造出一种以基本数学知识为支架的数学对象,让原本模糊的知识点清晰起来,从而联系到已知知识点,借助该构造好的数学模型,从而解决数学问题.一、构造函数,结合方程方程和函数之间是相互紧紧联系的,学生对于函数比较熟悉,对于构造法也比较好展开讨论.对于代 Construction method, that is difficult to solve mathematical problems, according to the conditions of the questions and conclusions contained in the characteristics, nature, change the direction of thinking problems, from a new perspective, new perspectives to understand the topic, to understand the topic, contact knowledge , And then between the conditions and conclusions, construct a mathematical object with basic mathematical knowledge as a support, so that the original fuzzy knowledge points clear, and thus linked to the known knowledge point, with the help of the mathematical model to solve Mathematic problems First, the constructor, combining equations and functions are closely linked with each other, the students are familiar with the function, the construction method is also better to start the discussion for the generation
