浅谈坐标系在中学数学中的应用 应用数学教育学专业

1浅谈在中学数学中坐标系的应用摘 要: 本文一开始介绍了一些坐标系的相关概念和在中学数学中学习坐标系的作用。通过对近几年的各地高考真题或模拟题的分析解答，给出了使用坐标系和一些常用于解决问题的公式和解决此类问题的一般步骤；坐标系是解析几何与代数运算的关键核心点，是解决数形结合问题的得力工具，本文从各个方面详细的介绍了数形结合思想和坐标系之间的相关关系，使数与形之间互相转化。让学生在学习数学的过程中，轻松应用坐标系，更能体现坐标系在数学中的地位,同时也能更好地帮助中学学生在学习此版块知识时，起到一个衔接作用。关键词:坐标系 中学数学 应用On the Application of coordinate system in Middle School MathematicsAbstract：In this paper, the concept of coordinate system and the significance of learning coordinate system are introduced at first. Based on the analysis and solution of the real or simulated problems in the college entrance examination in recent years, this paper gives the use of coordinate system and some formulas commonly used to solve the problems and the general steps to solve these problems. Coordinate system is the bridge between geometry and algebra, and it is a powerful tool to solve the problem of combination of numbers and shapes. This paper introduces the relationship between the idea of combination of numbers and shapes and the coordinate system, so that the number and shape can be transformed into each other. In the process of learning high school mathematics, students can easily use this knowledge point, which can better reflect the application of coordinate system in middle school mathematics, and at the same time, it can also help middle school students to learn this section of knowledge. Play a cohesion role.Key words: Coordinate system number combination vector method2目 录1 坐标系的概念及学习坐标系的意义.........................................21.1 坐标系含义........
