近几年,高考立体几何解答题的标准答案几乎清一色用的是坐标向量法(另一种为综合几何法).笔者认为:“非坐标向量”也应引起我们的重视.首先,非坐标向量也是向量,并且它是研究向量的起点和基础.其次,它具有较大的自由性,它对发展学生思维有很好的作用,坐标向量的这种作用相对较 In recent years, the standard answer to the three-dimensional geometry solution for college entrance examinations is almost the same as the coordinate vector method (the other is the comprehensive geometry method). The author believes that: “non-coordinate vector” should also cause our attention. First, the non-coordinate vector It is also a vector, and it is the starting point and foundation of the study vector. Second, it has greater freedom. It has a good effect on the development of student thinking. The role of the coordinate vector is relatively
