所有数学题目的求解都是从条件到结论的正确、有效的转化过程,可是很多题目的条件却不明确给出,称之为隐含条件.具体地说,隐含条件就是题目未明确给出,却可根据题意推出的有用条件,或者是已知的公式,定理等等客观存在的事实[1].能否在解题中快速找到题目中的隐含条件、快而准的完成解题,它能够在高考中体现考生的综合分析能力,实现高考的选拔功能,因此要在教学中加强训练.本文探究命题中隐含条件的常见隐含方式及怎样挖掘,以供参考.
All mathematical problems are solved from the conditions to the conclusion of the correct and effective conversion process, but many of the conditions are not clearly given, called the implied conditions. Specifically, the implied conditions are not given the title , But according to the questionable introduction of useful conditions, or known formula, theorem, etc. The objective existence of the facts [1] .To solve the problem can quickly find the subject of implicit conditions, fast and accurate completion of the solution It can reflect the comprehensive analysis ability of the examinees in the college entrance examination and realize the function of the college entrance examination selection.Therefore, it is necessary to strengthen the training in teaching.This paper explores the common implicit ways of the implied conditions in the proposition and how to mine for reference.
