本文指出应用向量解决立体几何中的度量问题,计算空间图形中的有关角度和距离时,“不必作出所要求的角和线段”。而要作出它们常常是很困难的,这正是用向量解决这类问题的明显优势之一.本文作者的这一认识,可以帮助我们提高应用向量的自觉性.
This paper points out that applying vectors to solve metric problems in solid geometry and calculating the relevant angles and distances in the spatial graphs “does not require the required corners and line segments”. It is often difficult to make them. This is one of the obvious advantages of using vectors to solve such problems. This knowledge of the author of this article can help us to increase the awareness of application vectors.
