一、转化法一个数学问题的解决往往离不开转化。有时候我们需要对所给的条件作深刻的理解，将条件转化为与问题的解决更加密切相关的条件，这种解题方法称为条件转化法；有时候我们需要在分析题意的基础上，将问题本身转化为更加简单，或者更加熟悉的数学问题，这种解题方... First, the transformation method A mathematical problem often can not be resolved. Sometimes we need to have a deep understanding of the conditions we have given and to translate the conditions into conditions that are more closely related to the resolution of the problem. This solution is called conditional conversion; sometimes we need to analyze the problem , The problem itself into more simple, or more familiar with mathematical problems, this problem square ...
