高中阶段的数学题目一般通过数字、线段、几何图形进行呈现,解题时根据题目所给的数字、公式、方程以及相关图形,对问题进行解析和求证。一般情况下,单独分析数据或图形,解题会较为困难。对此,我们可以运用数形结合思想进行分析,不但可以简化题目,更能激发学生的学习兴趣,避免出现因解题 High school mathematics topics are generally presented by numbers, line segments, geometry, problem solving according to the numbers given by the subject, formulas, equations and related graphics, the problem analysis and verification. Under normal circumstances, a single analysis of data or graphics, problem-solving will be more difficult. In this regard, we can use the idea of ​​combining numerical analysis, not only can simplify the subject, but also stimulate students interest in learning to avoid problems due to problems
