我们在解决立体几何、平面几何、解析几何问题时 ,如果能灵活地应用法向量的方法去解题 ,就会避开一些复杂的计算、繁琐的思维 ,使解答变得简捷 ,同时法向量也给我们提供一种全新的解题方法和途径 .下面是笔者在法向量教学过程中 ,就法向量法解题的一些体会加以整合 ,列举如下 When we solve the problems of solid geometry, plane geometry, and analytical geometry, if we can flexibly apply the method of normal vector to solve problems, we will avoid some complicated calculations and tedious thinking, so that the solution will be simple and the normal vector will also be To provide us with a new method and approach to solving problems. The following is the author in the process of normal vector teaching, some of the experience of the solution of the normal vector method to integrate, listed below
