数学问题中的已知条件是分析和解题的依据,但很多问题往往蕴藏着“隐含条件”.所谓“隐含条件”是指题目中虽给出但不明显,或没给出但隐含在题意中的某些条件.在解题过程中要充分挖掘这些隐含条件,或做好条件的转化,化隐为显;或根据题设把隐含在题意中的条件挖掘出来,化未知为已知,从中找到内在联系,这样能避免因忽视隐含条件而造成错解或解答不完整甚至造成解题困难. Known conditions in mathematical problems are the basis for analysis and problem solving, but many problems often contain “implied conditions.” The so-called “implied conditions” is given in the title but not obvious, or not Given but implicit in the title of some of the conditions in the process of solving problems to fully tap these implicit conditions, or do a good job of condition conversion, hidden implicit; or based on the subject implied in the inscription Of the conditions of the excavation, the unknown is known, to find the internal linkages, thus avoiding the negligence of hidden conditions caused by incomplete or wrong answer or even cause problems.
