在近几年高考中,解答题中的立体几何越来越青睐于用向量的方法来解决,但在实际操作过程中,很多学生在用这种方法来解题时还存在一定的困难.因此,我简单地谈谈立体几何中直角坐标系的建立、向量的 In the college entrance examination in recent years, the solution to the problem of solid geometry more and more favored in the vector method to solve, but in practice, many students in this way to solve problems when there are still some difficulties.Therefore, , I briefly talk about the establishment of Cartesian coordinate system in three-dimensional geometry, vector
