现实生活中蕴涵着大量的与数量和图形有关的问题,这些问题可以抽象成数学问题,用数学方法予以解决.我们在学习数学的过程中应该养成应用数学的意识.2013年各地中考试题中有不乏来自现实生活的试题,真正体现了数学从生活中来,到生活中去的理念.本文从2013年中考试题中选取三道源自现实生活的数学应用问题,与同学们分享.一、伸缩门例1(2013年舟山)某学校的校门是伸缩门如图1所示,伸缩门中的每一行菱形有
In real life, there are a great deal of problems related to quantity and graphics. These problems can be abstracted into mathematical problems and solved mathematically. We should develop applied mathematics awareness in the process of learning mathematics. There are many questions from the real life, truly embodies the concept of mathematics from life to life to go.This article from the mid-term exam in 2013 selected three from the practical application of mathematics, to share with students.One, Retractable door example 1 (2013 Zhoushan) A school’s school gate is retractable door shown in Figure 1, each retractable door diamond shaped
