猜想是人们依据事实,凭借直觉所作出的似真推测,是一种创造性的思维活动,它既是科学发现的先导,也是问题解决的一种手段.在着手解题之前进行大胆的猜想,对培养创造性思维和勇于探索的精神都大有稗益. 一、运用赋值法,进行猜想 有些没有明确给出结论的命题,如直接由条件寻求结论,可能很困难,这时可用特殊值代入验证,进行猜想,将有助于发现可能的结果或解题的方法.
Guessing is a plausible guess based on facts and intuition. It is a creative thinking activity. It is both a forerunner of scientific discovery and a means of problem solving. It takes bold conjectures before proceeding to solve problems. Creative thinking and the courage to explore the spirit are of great benefit. First, the use of valuation methods to make conjectures Some of the propositions that do not explicitly give conclusions, such as seeking the conclusions directly from the conditions, may be difficult, then special values can be used to validate Guess, will help to find possible results or solve problems.
