摘要
针对第二重要极限存在计算公式多样化及形式构造复杂化的问题,提出了解析第二重要极限的三步骤法。利用幂指函数的连续性处理1∞未定型极限,并将其归纳为判定类型、构造"1加"、指数倒数形式的三步骤,即可得到极限计算结果。三步骤法简化了第二重要极限的计算步骤,降低了第二重要极限学习和掌握的难度。
The study focuses on second important limit which has defects like two kinds of calculating formulae and excessive changes in calculation process.A new calculation algorithm was proposed in this pa-per and named second important limit three-step method.The solving process of indeterminate form limit was segmented into three specific steps.It is easy to master this algorithm without much theoretical knowledge with the method being more concise and practicable.
