试谈特例的解题功能徐新民（江苏通州市刘桥中学２２６３６３）特例是数学中的实验手段．从特例中认识一般，是数学解题中获取解题信息、寻求解题通道最基本的方法．本文拟就特例在数学解题中的功能作一浅析．一、判断功能一个命题若在特殊条件下成立，并不能确保在一般条... Try to discuss the problem-solving function of special cases Xu Xinmin (Liuqiao Middle School, Tongzhou, Jiangsu 226363) The special case is an experimental method in mathematics. To understand the general situation from a special case is the most basic method for obtaining problem solving information and seeking a solution channel in mathematical problem solving. This article proposes to analyze the function of special cases in mathematical problem solving. First, determine the function of a proposition if established under special conditions, and can not guarantee that in general ...
