立体几何的问题,究其根本就是解决点、线、面的位置关系的问题.新课程标准利用向量工具对空间平行、垂直、空间角和空间距离的解决赋予全新的思路,即用代数方法来求解传统几何问题.如果对空间平面进一步代数化,即用空间平面方程来解决相关问题,更有异曲同工之妙.湘教版高中数学选修教材2-1中,在章末练习中对空间平面方程给出了几种形式的方程,现对有关应用问题做几点探讨.
The problem of the three-dimensional geometry is simply to solve the problem of the positional relationship of points, lines and planes.The new curriculum standard uses vector tools to give a completely new idea to solve the problems of parallel, vertical, spatial angle and spatial distance in space, To solve the traditional geometric problems.If the space plane further algebraic, that is, using space plane equation to solve the related problems, more similarities and differences between the same .Xiangban version of high school mathematics elective textbook 2-1, at the end of the exercise on the space plane equation Given several forms of equations, the current application of the issue to do some discussion.
