空间向量是高中数学中的重要内容,是处理角度和距离问题的重要工具,也是高考考查的重要内容之一.运用向量方法研究立体几何问题思路简单,模式固定,避免了几何法中作辅助线的问题,从而降低了立体几何问题的难度.下面,我们就以具体的例子来阐述怎样运用向量解决角与距离问题.
Spatial vector is an important part of high school mathematics, an important tool to deal with angle and distance problem, and also one of the important contents of college entrance examination.Using vector method to study the problem of three-dimensional geometry is simple in thinking and fixed in pattern, Of the problem, thereby reducing the difficulty of three-dimensional geometric problems below, we will use a specific example to illustrate how to use vectors to solve the problem of angle and distance.
