It is a beautiful day. You leave your calculus class feeling
sad and depressed. You aren't sad because of the class itself.
On the contrary, you have the finest mathematics professor around
and you just learned an amazing integration technique: Integration
by Parts. You aren't sad because it is your birthday. On the
contrary, you are still young enough to actually be happy about
it. You are sad because you know that every time you learn something
really wonderful in calculus, a wild-eyed stranger runs up to
you and shows you a "proof" that is false. Sure enough,
as you cross the Michigan Street, he is waiting on the other
"Good morning, Sonny," he says.
"I just learned integration by parts. Let me have it."
"What do you mean?" he asks.
"Aren't you going to run around telling me that all of
math is lies?"
"Well, if you insist," he chuckles and hands you
a piece of paper:
"Hey," you say, "I don't get it! You did everything
"Yup!" says the hungry looking stranger.
"But ... zero isn't equal to negative one!"
Find the error in the wild-eyed stranger's reasoning.
Don't forget to explain your answer
as clearly as possible.
