If I'm who I am because I'm who I am and you're who you are because you are who you are, then I'm who I am and you're who you are.
If,on the other hand, I'm who I am because you're who you are, and if you are who you are because I'm who I am, then I'm not who I am and you're not who you are. |

常函数和指数函数e的x次方走在街上,远远看到微分算子,
常函数吓得慌忙躲藏,说:“被它微分一下,我就什么都没有啦!” 指数函数不慌不忙道:“它可不能把我怎么样,我是e的x次方!” 指数函数与微分算子相遇。 指数函数自我介绍道:“你好,我是e的x次方。” 微分算子道:“你好,我是‘d/dy!’ |
