数学应用问题通常以文字表述的形式描述一种问题情境,需要通过阅读理解将其转化为数学问题,或抽象出其存在的数学模型.因此,解答应用问题的关键在于能否读懂题意、抽象出数学模型.本文主要阐述高考中应用问题的常见题型及其解法.1与函数、方程(组)、不等式(组)有关的题型涉及长度、面积、造价、利润等最优化问题是应用题主要考查的方面.解决这类问题一般要利用数量关系,列出有关解析式,然后运用函数、方程、不等式等
Mathematical application problems usually describe a problem situation in the form of textual expression, which needs to be translated into mathematical problems by reading comprehension or abstraction of the mathematical model of its existence.Therefore, the key to answering application problems lies in the ability to read the questions, Abstract the mathematical model.This paper mainly expounds the common question types and their solutions in the college entrance examination.1 The questions about the function, equation (group) and inequality (group) involve the optimization problems of length, area, cost and profit The main test aspects of the application problem.To solve this type of problem generally use the relationship between the number of listed analytical, and then use the function, equation, inequality, etc.
