解数学客观题的常用方法,主要分直接法和间接法两大类.直接法是解答客观题最基本、最常用的方法.但高考的题量较大,如果所有客观题都用直接法解答,不但时间不允许,甚至有些题目根本无法解答.因此,我们还要掌握一些解答客观题的间接法.本文着重探讨巧用特殊法解数学客观题,以唤起同学们学习数学的兴趣,激发同学们的求知欲!
Solving objective problems of mathematics commonly used methods, mainly two kinds of direct method and indirect method .Direct method is to answer the objective questions the most basic and most commonly used method.But the question of college entrance examination is large, if all objective questions are answered by direct method , Not only the time is not allowed, and even some questions can not be answered at all.Therefore, we also need to master some indirect methods to solve the objective questions.This paper focuses on the use of special law to solve mathematical objective questions in order to arouse students’ interest in learning mathematics and stimulate students Their curiosity!
