9. 从勾股定理聊到它的种种扩展

from 大老李聊数学(全集)

说起勾股定理,我认为是中学数学中定理证明最优美的一个。其实你现在回想一下整个中学教的数学,虽然内容很多,但是真正教授过的,能称之为“定理”的命题其实聊聊无几,大多数只能叫公式。几何里叫定理的虽然多了一下,什么三角形全等有很多判定定理,性质定理也有一堆,但是这些定理大多数都太简单或者太直观,所以证明过程远不谈不上优美,而且以人名命名的定理也只有这一个,不信你自己好好回想一下中学数学,是不是只有这个以人名命名的叫毕达哥拉斯定理的定理,这足以说明这个定理的重要。从勾股定理聊到它的无数种扩展形式....上期趣题的答案:本期趣题:请将1234表示成四个平方数之和,可以用1,不可以用0哦。
