想必细心的同学都会有这样一个体会 :在解数学题时 ,有些看似“高不可攀”的题目 ,若能打破常规 ,不拘泥于题目表面所展现的知识点 ,如用解析法证代数题 ,用三角代换解不等式题 ,或用函数的观点分析几何题 ,甚至多种数学方法交叉使用 ,都有可能收到意想不到的效果 ,给人“柳暗 Presumably careful classmates will have such an experience: When solving math problems, some seemingly “unreachable” topics, if they can break the convention, do not stick to the surface of the topic to display the knowledge points, such as the use of analytical forensic algebra problems The use of triangles to solve inequality problems, or analysis of geometric problems from the point of view of the function, and even the use of multiple mathematical methods, may have unexpected results, giving people
