The plane vector is a new addition to the mathematics experiment textbook for senior high schools. The plane vector has both a geometric “shape” and an algebraic “number”. It is not only an operation object in mathematics, but also a solution to mathematical problems and physics. The computational tools and methods of the problem. The following examples illustrate the application of vectors in analytical geometry problems. The use of vector knowledge to solve analytical geometry problems is:
