数学应用题本质上是数学模型方法.因此解答应用题就是在阅读材料,理解题意之后,将实际问题抽象转化成数学问题,建立相应的数学模型.然后利用数学知识对数学模型进行分析、研究,得到数学答案,再把数学答案返回到实际问题中去.第一阶段——建模;第二阶段——解模.解应用题的困难主要在于建模和解模.相当一部分应用题叙述冗长,读起来有点儿让人心烦.但细细地品味下去,一旦领会其实质,又觉得既简单又颇有趣味.你看——[例1]某市场信息中心采集了一些供求信息,其中对菜椒市场的需求量与供给量进行调查后
The mathematics application problem is essentially a mathematical model method. Therefore, the solution to the problem is to read the material and understand the meaning of the problem, then translate the actual problem into a mathematical problem and establish a corresponding mathematical model. Then, use mathematical knowledge to analyze and study the mathematical model. , Get the mathematics answer, and then return the mathematics answer to the actual problem. The first stage - modeling; The second stage - solving the model. The difficulty of solving the problem is mainly in modeling and solving the model. A considerable part of the application title is lengthy It’s kind of annoying to read, but once you’ve tasted it, once you understand what it is, you think it’s both simple and interesting.
