应用题通常以实际生活为背景主要考查学生的建模能力以及分析问题、解决问题的能力.三角是一个非常重要的解题工具,广泛应用于物理学、航海、建筑设计、测量、国防等社会生活实践中.以三角为背景的应用题多次出现在高考试题中.解答三角背景应用题一般分为以下四个步骤:(1)审题:读懂题意,理顺问题中的条件和结论,找到关键量;(2)建模:将文字语言或者图形语言“翻译”转化为数学符号语言,结合
Application questions are usually based on the actual life as the background to examine students’ ability to model and analyze problems as well as to solve problems. Triangle is a very important tool for solving problems and is widely used in the fields of physics, navigation, architectural design, measurement, national defense and other social Life practice .Three angle for the background of the application questions appear in the college entrance examination questions many times.To answer the triangular background application questions are generally divided into the following four steps: (1) exam questions: read the questions, straighten out the conditions and conclusions of the problem , Find the key quantity; (2) modeling: the text language or graphic language “translation ” into mathematical symbolic language, combined
