一个很好的函数

一个白衣书生出游,于湖光山色之中寻得一寺,寺中有一老僧。二人相谈甚欢,便携手入院。老僧见书生谈吐不凡,遂生考较之意。见院内瓜果藤蔓,老僧出上联曰:”一阶石桌两个闲人三尺小院,四顾春色静看五月石榴。”书生羽扇轻摇,蛋定一笑:”这有何难:五维空间四次齐次三角函数,二重积分必然一致连续。

哆塔微博上告知了一个很好的实函数\[y = x\left( {\sqrt {\cos \left( {2\pi x} \right) - 1}  + 1} \right) + 0 \cdot \ln x.\]

图象是$(1,1),(2,2),\cdots,(n,n),\cdots$这些离散的点.
