同学们知道,反证法是数学中的重要证明方法.牛顿曾说过:“反证法是数学家最精妙的武器之一.”但不少同学由于对反证法的重要性认识不足,运用反证法的意识不强,就是偶尔使用反证法证明一个命题也经常出现失误.本文拟就反证法的运用提出几点建议.一、增强运用意识由于反证法不是现行高考的考查重点,再加上反证法推理论证方式的独特性,很多同学 Students know that the law of proof is an important proof method in mathematics.Newton once said: “The law of proof is one of the most sophisticated weapons for mathematicians.” But many students, due to lack of understanding of the importance of counter-proof, Is not strong, is the occasional use of proof to prove a proposition often mistakes.This article intends to make some suggestions on the use of proof.First, to enhance awareness of the use of proof as the law is not the focus of examination of the current college entrance examination, coupled with the uniqueness of proof of argument Many students
