A constant function and e^x are walking on Broadway.
Then suddenly the constant function sees a differential
operator approaching and runs away.
So e^x follows him and asks why the hurry.
"Well, you see, there's this differential operator coming this way,
and when we meet, he'll differentiate me and nothing will be
left of me...!"
"Ah," says e^x, "he won't bother ME, I'm e to the x" and he walks on.
Of course he meets the differential oper |
