在数学解题中对问题通过转化而求得解决 ,是基本的数学思想 .从思维结构上看 ,首先应对一些基本原理、基本法则和典型问题的解法及结论形成深刻的认识 ,当我们遇到陌生或繁难的问题时 ,可通过这些问题和基本问题的关系 ,化生为熟、化繁为简来解决问题 .转化的方式 ,有时是等价 Solving problems through solving problems in mathematical problem solving is a basic mathematical idea. From the perspective of thinking structure, we should first form a profound understanding of some fundamental principles, basic principles and solutions to typical problems and conclusions when we encounter When problems are unfamiliar or difficult, problems can be solved through the relationship between these problems and basic issues.
