转化能力是指将问题通过适当的方式归结为已有知识或能力范围,从而使问题获解的一种能力。转化能力是一种创造思维能力,是解决问题的重要思维方式,在学习中加强这方面的训练,有利于培养自我思维的灵活性和数学素养。一、命题的等价转化利用命题的等价关系(即充要条件)把问题转化为所熟悉或容易处理的问题,即利用逆否命题与原命题同真同假进行等价转化。
Transformative ability refers to a problem that can be solved by the problem being reduced to the existing knowledge or ability range through the proper way. Transformation ability is a kind of creative thinking ability, which is an important way of thinking to solve the problem. Strengthening the training in this aspect is conducive to cultivating the flexibility and mathematical quality of self-thinking. I. The Equivalent Transformation of Propositions Use the equivalence relation of propositions (that is, the necessary and sufficient conditions) to convert the problems into familiar or easily handled problems, that is, use the inverse no proposition and the original proposition to carry out the equivalent transformation with the true homosexuality.
