向量是近代代数学中重要和基本的数学概念之一,它是沟通代数、几何的一种工具,其具有“数”与“形”两个特点,这就使得向量成了数形结合的桥梁,因此在实际问题中往往要从“数”与“形两个方面来建构和研究向量。具体地说,向量的几何表示、向量的三角形运算法则等等,都是从几何的角度对向量的研究,而向量
Vector is one of the most important and basic mathematical concepts in modern algebra. It is a tool for communication algebra and geometry. It has two characteristics of ”number “ and ”shape “, which makes the vector into a number Therefore, in practical problems, it is often necessary to construct and study vectors from the two aspects of ”“ and ”shape." Specifically, the geometric representation of vectors, the triangular algorithm of vectors and so on are From the geometric point of view of vector research, and vector
