近几年的“四大联盟”——北约、华约、卓越与京都等自主招生试题中,涌现出了很多求极限或利用极限思想的命题.笔者对这类问题进行了分析,总结出了几个模型,供大家参考,并期望对备考与教学有所启示.本文整合的是“极限模型”类比数列通项公式与函数的关系,离散型数列的极限是连续型函数极限的特殊情形,所以我们只需识记并灵活运用连续型极限的几个模型,就可以应对一些自主招生试题.
In recent years, “four alliances” - NATO, Warsaw Pact, Excellence and Kyoto and other self-enrollment questions, there emerged a lot of ideas for the limit or the use of the limit of ideas.The author analyzes these problems, concluded A few models for your reference, and hope for the pro forma and teaching enlightenment.This article is integrated “limit model ” analog series of general formulas and functions, the limit of discrete series is the continuous function limit Therefore, we only need to recognize and flexibly use several models of continuous limit to deal with some self-enrollment questions.
