随着坐标法的引入,很多几何问题通常可以转化为代数问题进行运算、求解,导致很多学生习惯于将几何问题代数化,对于“用代数的方法分析图形”比较注重,反之,对几何问题中反映的几何特征的认识不足,缺乏“用图形研究数和式”的习惯.利用代数方法可以解决几何问题,但往往需要大量 With the introduction of the coordinate method, many geometric problems can usually be converted into algebraic problems for operation and solving, resulting in many students are accustomed to algebraic geometric problems, for the “analysis of graphics using algebraic methods” pay more attention to the contrary, the problem of geometry The lack of understanding of the reflected geometric features and the lack of the habit of “researching numbers and formulas using graphs.” Algebraic methods can solve geometric problems, but often require a lot of
