0. 基本定义 Singularity (mathematics) 数学上的奇异性一般是指,函数在该点未定义(not defined,比如取值为无穷),或者不可微(fails to be well-behaved). 1. 举例 f(x)=1x:在 x=0 处未定义: g(x)=|x|:在 x=0 处不可微(左导数不等于右导数): y2=x 也就是 y=x√,x≥0,在点 (0,0) 处 虽然有定义,但是在 x=0 处为 vertical tangent,也即在该点处的导数为无穷大(又因为导数其…

最近研究slot 算法,看了大量的英文资料,因为母语中文,一直使用中文的英文小白来说,好心塞,悔不当初没学好英文. 下文是从众多的英文中摘录的唯一能够看明白的概念.先给自己留着,到时候深入研究可以看 Commonly used mathematical concepts in gambling: Combin Function The Combin Function is an Excel function that calls on combinatorial mathematics to p…
