1.本单元重、难点分析平面向量是高中新教材增加的内容之一,具有代数形式与几何形式的双重特征.在学习的过程中,应按照这样的一个过程来认识:什么是向量(即向量的定义)——向量之间的关系及其运算法则(即解决有关向量问题应遵循的法则)——向量的应用.向量在高中数学中起到工具 1. This unit’s heavy and difficult analysis of plane vectors is one of the contents of the new high school textbooks. It has the dual features of algebraic forms and geometric forms. In the process of learning, it should be understood in accordance with such a process: What is a vector (ie, The definition of vectors) - the relationship between vectors and their algorithms (that is, the rules that should be followed when solving vector problems) - the application of vectors. Vectors are used as tools in high school mathematics
