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 operator after a short distance.

e^x: "Hi, I'm e^x"

diff.op.: "Hi, I'm d/dy"

No, think of the fact that e^x was cocky about how getting differentiated couldn't do anything to him

Now, what is d/dy (e^x)?

He is differentiating d/dy, not d/dx.

It's not all that funny, IMO, but it's pretty good.

d/dy(e^x) = e^x*x'

Sounds like some people need to retake calc 1. d/dy is differentiation with respect to y. Since e^x is a function of x, d(e^x)/dy is 0.

iirc d(e^x)/dy = e^x, so e^x wasn't worried. but i still don't get the convo at the end either.

EDIT: i just read the other posts. now i get it. sheesh it's been a long time since calc.

No
You are differentiating with respect to Y
therefore, you treat e^x as a constant
d/dy of any constant is zero

you know that reminds me of.

For those of you who watch Cartoon Network. Dexter Tells this Elabert math joke that makes no blood sense but you can't help but laugh because it's so stupid.

no, you must implicitly differentiate.

actually i thought that. but his way is also correct, because x could be a function of y, and it yields the correct answer (0) if it is constant.
