Calculus Joke

Courtesy of my math professor:

Two mathematicians go to a bar after a rigorous day of number crunching. After a few drinks, the first mathematician begins to lament the current state of the general public's mathematical knowledge.

"People just don't know their calculus anymore!"

"I don't think that's true," replies the second, " I bet they know more than you think".

"Let's make it a real bet then," says the first, " I'll bet you $100.00 that if I ask *her* a simple question, she won't be able to answer at all"

The subject of the bet was to be a particularly ditzy looking young waitress.

"You're on"

Before the bet commences, the first runs to the restroom. In the interim, the second calls the waitress over and informs her of the nature of the bet, telling her he'll give her $10 if she answers his question with "x cubed".

"X cubed," She repeats to herself, "I think I can handle that".

The first mathematician returns, ready to start the bet. They call the waitress back over and the second pretends not to know her, saying

"Excuse me miss, but I was hoping you could answer a simple question for me, what is the indefinite integral of 3x squared?"

"That's simple, it's x cubed!"

Dumbfounded, the first man admits defeat and hands over $100 to his friend. The waitress begins to walk away, but then quickly turns around.

"Hey, I forgot something," she exclaims, "Plus an arbitrary constant C!"
