利用平面向量解决解析几何问题,是当前高中数学教学的重要内容之一,越来越多的教师开始重视培养学生使用向量解决解析几何问题的能力.本文结合几个例题简要地介绍平面向量在解析几何中的一些应用,希望能对高中数学教师的工作带来一定的启发.一、平面向量与解析几何的关系平面向量的数量积是高考的8大C级要求之一,向量的知识与其它内容都有交汇点.在解析几何中,有些问题使用常规方法解题可能会比较麻烦,但如果使用向量的知识去解决解析
The use of plane vector to solve the problem of analytic geometry is one of the most important contents of high school mathematics teaching at present, more and more teachers begin to attach great importance to the ability of students to solve the problem of using analytic geometry to solve geometric problems.This paper briefly introduces planar vector in analyzing Some applications in geometry, hoping to bring some inspiration for the work of high school mathematics teachers.First, the relationship between plane vector and analytic geometry The number of plane vectors is one of the eight major C-level requirements of the college entrance examination, vector knowledge and other The content has a meeting point.In the analytic geometry, some problems may be more troublesome to use the normal method to solve the problem, but if you use the vector knowledge to solve the resolution
