在用数学归纳法证明与正整数有关的不等式时,关键一步是由n=k到n=k+1的推理过程.而有时这一推理过程无法实现,或推出矛盾.本文就几点疑惑的对策例析如下.一、合理运用假设例1用数学归纳法证明
When mathematical inequalities prove positive inequalities, the key step is the inference process from n = k to n = k + 1. Sometimes this inference process can not be implemented or the contradiction arises. Countermeasure analysis as follows.First, the rational use of hypotheses Example 1 proved by mathematical induction
