数学解题中的构造法是指根据题目中现有的条件,进行数学模型的构建,其核心思想是将未知量转变为已知量,从而解决数学问题.构造法的内核是“转化”的思想,与其他解题方法的最突出区别就在于构造法是在解题的过程中构造与原问题相关的辅助问题,从而再对原问题进行解答.在高中数学中,构造法常用的形式有以下几种:方程、图形、向量、函数、数列的构造等.本文就函数的构造和向量的构造举例说明.一、函数的构造
The constructive method in mathematical problem solving is to solve the mathematical problem by transforming the unknowns into known quantities according to the existing conditions in the subject and constructing the mathematical model.The core of the constructor is The most prominent difference between the thought and other solution methods lies in the fact that the construction method is to construct the auxiliary problem related to the original problem in the process of solving the problem so as to answer the original problem again.In the middle school mathematics, There are several forms: equations, graphics, vectors, functions, the construction of the sequence, etc. In this paper, the structure of the function and the construction of vector examples. First, the structure of the function
