向量是中学数学中除数量外接触到的另一类量.高中数学《代数》第二册(甲种本)在复数的学习中引入了这一概念(向量最先出现在高一物理的力学部份,那里称为矢量.)本文拟用向量的基本常识导出一个简单的向量式来讨论一些几何问题,旨在沟通代数与几何之间的知识联系,帮助加深对向量的认识,探讨几何问 Vectors are another type of quantity that comes into contact with mathematics in high school mathematics. High school mathematics “Algebra” Volume 2 (A type) introduces this concept in the learning of plurals (vectors first appeared in physics of high physics. Part, where it is called vector.) This article uses vector basic knowledge to derive a simple vector formula to discuss some geometric problems. It aims to communicate the knowledge connection between algebra and geometry, help to deepen the understanding of vectors, and discuss geometry
