1.重、难点分析引入向量研究几何是几何代数化的需要.它一方面能使我们了解一些近代数学知识,开拓视野;另一方面,为解决立体几何中某些用传统的纯几何方法解决时技巧性大、随机性强的问题提供一些通法,降低了解题难度.在平面向量的基础上加以推广,就可得到空间向量的运算体系. 1. Heavy and difficult to analyze the introduction of vector geometry is the need of geometric algebra.It not only enables us to understand some modern mathematics knowledge and broaden our horizons.On the other hand, in order to solve some of the solid geometry with traditional pure geometric method When the skill is large, the randomness of the problem provides some common method to reduce the difficulty of solving the problem.On the basis of the plane vector to be extended, you can get the space vector computing system.
