【摘要】运用隐含条件解题是中学数学中的重要题型,它内容丰富,涉及面广,解法灵活多变,常使学生感到心中无数,因而学生在解这类题时往往容易丢分,因而倍受命题者的青眯,成为高考中一道亮丽的风景。隐含条件往往是解决问题的关键,这些条件容易被忽视而造成错解。因此,解题时,正确地挖掘、辨析题目中的隐含条件并充分利用,对于排除干扰,正确地解决问题至关重要。

  本文在每节的内容中,先是对方法或者问题进行综合性的叙述,再以典型例题的形式出现,示范性的对典例进行详细的解答和分析。每个典例的选取,又尽量综合到代数、三角、几何几个部分重要章节的数学知识。

[Abstract] Using implied conditions to solve problems is one of the important topics for middle school mathematics. It is rich in content , covers a wide range and flexible in solution ,so it often makes students feel heart countless and tend to lose points when solving this kind of questions which makes originators like to design this kind of questions in the university entrance exam. Implied conditions are often the key of resolving a problem, but they are easily neglected and cause the wrong solutions. Therefore, mining and making full use of the implied conditions is very important when solving mathematics problems.

  In this paper, the content of each section, In this paper, the contents of each section, first on the method or a comprehensive description of the issue, then the form of the typical examples, exemplary of the typical example of the detailed answers and analysis. Typical example of each selection, and as far as possible integrated into algebra, trigonometry, geometry of several chapters of the mathematical knowledge of some important.

[Key words] implied condition    the university entrance exam of mathematics   ability to solve problems

上传会员 lxswj2006 对本文的描述:所谓“隐含条件”,是相对“显性条件”而言的,是数学问题中已知条件(显性条件)没有明确表明,且对解决问题起至关重要的一些条件,如数学问题“幕后”所固有的性质、公式等......
