构造法作为一种具有创造性和技巧性的数学思想方法,在初中数学解题中被广泛应用.原因在于,在处理某些问题时,利用常规方法解题比较困难而利用构造法往往能起到事半功倍的效果.运用构造法将问题与我们所熟知的理论联系起来,以此来构造出恰当的数学模型来清晰地反映出问题的实质,进而寻求解决问题的方法.下面举例对构造法在中学数学中的应用做些简单的阐述.一、构造方程1.通过观察题目特点极其条件,构造“一元一次方程”来
As a kind of creative and skillful mathematical thinking method, tectonic method is widely used in junior high school mathematics problem solving, because it is more difficult to solve the problem by using the conventional method and the tectonic method can often play a role in dealing with certain problems Use the construction method to connect the problem with the well-known theory, in order to construct the appropriate mathematical model to clearly reflect the essence of the problem, and then to find ways to solve the problem.For example, the construction method in high school Mathematical applications to do some simple exposition.One, the construction of the equation 1 by observing the characteristics of the subject extremely conditions, the construction of “a dollar equation” to
