建模问题是历年中考的常考题,建模问题之重要,正如法国著名数学家笛卡尔所说:“我们所解决的每一个问题,将成为一个模式,以用于解决其他问题”.利用一次函数或反比例函数、方程(组)、不等式、三角函数等知识,设计出不同的方案或制定一个最佳方案解决实际问题,是中考建模问题的重要内容.解这类问题的关键是通过对问题原始形态的分析、联想和抽象,将实际问题转化为一个数学问题,即构建一个数学模型.
The modeling problem is a common test question in the past years. The problem of modeling is important. As Descartes, a famous French mathematician, states: “Every problem we solve will be a model for solving other problems.” It is an important part of the senior high school entrance examination modeling problem to design different solutions or to develop an optimal solution to solve practical problems by using first-order functions or inverse proportion functions, equations (groups), inequalities, trigonometric functions, etc. The key to solving such problems is Through the analysis of the original form of the problem, association and abstraction, the actual problem is transformed into a mathematical problem, that is, to construct a mathematical model.
