向量是中学数学的一个核心概念.它作为一种既有大小又有方向的量,有形的特征,可以通过构造向量来处理代数问题,使问题直观化;又具备数的特点,可以将几何问题坐标化、符号化、数量化,从而将推理转化为运算.平面向量是高中数学的重要内容,是数形结合思想的典型体现.近几年高考对平面向量知识的命题,既充分体现自身知识结构体系命题形式的多样化,又保持与其他知识交汇的命 Vector is a core concept of high school mathematics.As a quantitative and directional quantity and tangible feature, it can deal with algebraic problems by constructing vector to visualize the problems and has the characteristics of number, Coordinate, symbolization, quantification, and thus reasoning into arithmetic.Plane vector is an important part of high school mathematics, is a typical embodiment of the combination of number and shape.Position vector in recent years college entrance examination on the subject, not only fully reflect their own knowledge Diversification of propositional forms of structural systems, while maintaining the intersection of other knowledge and life
