提到向量的应用,很多人会想到用向量的数量积求几何图形中的角、距离,或处理平行与垂直,老师是这样教的,学生是这样学的.其实向量应用的本色应该是用纯粹的向量运算来处理几何中的位置、大小关系,这样的应用恰恰是教学中的薄弱环节,如果不注意及时补上这一课,久而久之,应用向量 Mentioned the application of vector, many people will think of using the number of vector product geometry and angle, distance, or parallel and vertical processing, the teacher is teaching this, the students are so learning .In fact, the nature of vector application should be used Pure vector operations to deal with geometric position, size, the application is precisely the weak link in teaching, if not pay attention to make up for this lesson, as time passes, the application vector
