我们遇到问题时 ,在对问题作细致观察的基础上 ,展开联想 ,以唤起对有关旧知识的回忆 ,把待解决或未解决的问题 ,通过某种转化过程 ,归结到已经解决或比较容易解决的问题中去 ,最终求得原问题的解决。这种方法称为归与转化的思想方法。化归与转化的思想方法是数学学习中最重要 When we encounter problems, we make associations on the basis of careful observation of the issues to evoke memories of old knowledge, and resolve the unsolved or unresolved problems through certain conversion processes to the point where they have been solved or are relatively easy to solve. Solve the problem and finally solve the original problem. This method is called the thought method of conversion. The method of transformation and transformation is the most important in mathematics learning
