向量是解析几何的基础，它不仅能表示几何意义，还具有数的运算规律，可将代

Vector is the basis of analytic geometry. It can not only express geometric meaning, but also has the law of number operation, and can convert algebra and geometry to each other. The introduction of vectors can make the process of solving certain geometric problems easier and more convenient, and it plays an extremely important role in plane geometry and solid geometry. This article summarizes the related definitions and theorems of vectors in detail, and focuses on some commonly used calculation methods in vectors. Some examples are used to show the relevant applications of vector analysis in plane geometry and solid geometry, as well as the advantages of vector method compared with traditional methods, to show its important role in analytic geometry, and to give a brief explanation.

Vectors are the basis for parsing geometry, which not only represents geometric significance, but also has the operation law of numbers, which convert algebra and geometry to each other.
