向量是数学里面的一个重要内容,从初中开始接触向量的概念,在高中阶段向量开始发挥一些独特的作用,深刻理解向量的定义以及灵活使用向量的方法往往可以起到意想不到的效果。本文通过介绍平面向量的一些特殊方法来说明向量的灵活性和重要性。 Vector is an important part of mathematics. Starting from the concept of contact vector in junior high school, vector starts to play some unique roles in high school. It is often not surprising that a deep understanding of the definition of vector and the flexible use of vector approach can produce unexpected results. This article describes the flexibility and importance of vectors by introducing some special methods of plane vectors.
