数学归纳法——作为数学命题证明的基本方法,可以完成对许多与正整数相关命题的证明.其证明的关键是如何实现从“n=k 时原命题成立”(这个命题不妨称之为“假设命题”)到“n=k+1时原命题成立”(这个命题不妨称之为“目标命题”)的过渡.刚学过时,学生往往运用自如,觉得特神,待到高三复习综合时,它却往往被学生所遗忘.因此,教师应不失时机地使用它.当然,任何一种方法都不是万能的,也不是唯一的,应该都有它的局限性,数学归纳法也
Mathematical induction - as a basic method of proving mathematical propositions, you can complete proofs of many propositions related to positive integers. The key to the proof is how to implement the original proposition from “n=k” (this proposition may be called “ Assume the transition from the proposition ”) to “n=k+1 when the original proposition is established” (this proposition may be called a “target proposition”). Just after learning, students often feel comfortable and feel special, until the third grade review synthesis. However, it is often forgotten by students. Therefore, teachers should use it without losing the opportunity. Of course, any method is not omnipotent, nor is it unique, it should have its limitations, mathematical induction also
