反证法是高中数学中一种非常重要的证明方法,一般用于直接证明条件较少,关系不明确,问题形式较抽象,而其反面较具体、较容易入手的情况。本文作者以反证法为研究对象,通过归纳反证法的题型,以对此数学证明方法作了一个系统的研究。 Proof-of-evidence is a very important proof method in high school mathematics. It is generally used to directly prove the condition is less, the relationship is not clear, the problem is more abstract, and the opposite is more specific and easier to start with. In this paper, the author takes the evidence-based method as the research object and makes a systematic study of the mathematical proof method by inducting the types of the proof-of-concept method.
