方法一坐标法向量是高中数学的新增内容,借助向量这一工具,可对一些传统解法中较为繁琐的问题定量化获解,从而降低思维难度,增强可操作性,尤其是在求解或处理空间角、空间距离、空间位置关系的计算、证明等问题时,用向量方法可以最大限度地避开思维的高度转化,避开添加各种辅助线的难处,有利于我们较好地解决问题. The method-coordinate normal vector is a new addition to high school mathematics. Using the vector tool, it can quantify some of the more tedious problems in traditional solutions, thereby reducing the difficulty of thinking and enhancing operability, especially in solving or processing. When the problems of space angle, spatial distance, spatial position relation calculation, and proof are solved, the vector method can avoid the high transformation of thinking to the greatest extent, avoid the difficulties of adding various auxiliary lines, and help us solve problems better.
