立体几何问题是高中数学中的重要组成部分,也是高中数学中的重难点。因此,必须学好高中数学立体几何的相关知识点,将具体的解题方法进行总结归纳,进一步活学活用,做到在解答不同的立体几何的数学问题时,能够转化为相对应的解题方法,举一反三。根据深入的研究学习,关于立体几何问题的解析方法主要分为两种,一种是通过法向量的应用将立体几何转化为向量问题,建立直角坐标系进行解答,另外一种是通过建立函数关系,运用函数的性质和图像进行解答。本文将针对这两种解析方法进行具体的阐述。
Three-dimensional geometry is an important part of high school mathematics, but also a heavy difficulty in high school mathematics. Therefore, we must learn high school mathematics solid geometry related knowledge points, the specific problem-solving methods to summarize and further learn to use, so that in solving the three-dimensional geometry of mathematical problems, can be transformed into the corresponding problem-solving methods ,learn by analogy. According to the in-depth research and study, there are mainly two kinds of methods to solve the three-dimensional geometric problems. One is to convert the three-dimensional geometry into a vector problem through the application of the normal vector, set up a rectangular coordinate system to answer, the other is through the establishment of functional relationship , Use the nature of the function and image to answer. This article will address these two analytical methods to elaborate.
