我们学过很多的定理.它们各具特色,给我们解题带来方便.在牢记定理的同时,你对它们是否有过深一层的研究?我认为,定理的证明过程十分重要,它不仅能够体现出多种数学思想,还能加深对定理的理解.下面向大家介绍两个例子. We have learned a lot of theorems. They have their own characteristics, and they bring convenience to us. When you keep in mind the theorems, do you have a deeper level of research on them? I think that the proof process of the theorem is very important, not only Can reflect a variety of mathematical ideas, but also to deepen the understanding of the theorem. Here to introduce two examples.
