展示十种递推公式模型,它们是对参考文献和各省高考试题的提炼。由于参考文献中所给出的递推解法都是笼统的,分类讨论也不够完善。经过对每一递推公式仔细的揣摩、详尽的分类讨论,给出了变式模型等较为完善的解题模式。通过对各种类型模式的探究,提炼了解决递推问题的常用方法。 Demonstration of ten recursive formula model, they are references and provincial college entrance examination questions refining. Due to the recursive solutions given in the references are general, classification discussion is not perfect enough. After careful examination of each recurrence formula, exhaustive classification and discussion, a more complete problem solving model such as a variant model is given. Through the exploration of various types of patterns, the common method of solving recursion problems is refined.
