数学解题中隐含条件的挖掘与转化

The Excavation and Transformation of Implied Conditions in Solving Mathematical Problems

在数学解题过程中,很多同学思维方式呆板直接,考虑问题公式化、模式化,不能抓住题目条件中的隐含条件,从而使解法得以简化。从五个方面,以例题形式给出不同的解题方法,意在拓宽解题思路,挖掘题目中的内涵,将复杂问题转化为简单问题,使大家在数学学习中多角度、深层次地分析题目的要求,领会题目考察的目的,从而得到意想不到的收获。

In the mathematics problem-solving process,many students＇ way of thinking is so rigid and limited by formulations and models that they fail to get the implied conditions which simplify the solution.Different problem-solving methods are given by examples from five aspects to broaden the problem-solving ideas.In mathematics study,it is important to find the implied conditions,which will simplify complicated problems.
