解析几何的本质是用代数的方法研究几何问题,解几知识中,蕴含着深刻的数学思想,对解几本质的考查往往通过对其思想应用的考查得以体现。首先是由解几本质特征所决定的函数与方程思想,数形结合思想,其次是研究几何问题常用到的化归与转化的思想方法,分类与整合的思想方法,一般与特殊的思想方法等。一、数形结合思想解析几何的基本思想就是数形结合,因为数与形是数学中最 The essence of analytic geometry is the use of algebraic methods to study geometric problems, solving a few knowledge, contains a profound mathematical thinking, the nature of the solution to several tests often through the application of its thinking to be reflected. The first is the solution of several essential features of the function and the idea of ​​the equation, the number of ideas combined with the second is to study the geometry of the commonly used methods of conversion and transformation of ideas, methods of classification and integration, general and special methods of thinking . First, the number of ideas with the basic idea of ​​analytic geometry is the combination of numbers, because the number and shape is the most mathematical
