Re: Most useful thing learned in Calc

Well, I can't think of anything at the moment...I think I learned something...

but here's something interesting:
The solid created by the graph of 1/x rotated around the x-axis has finite volume but infinite surface area. As my math teacher said, you can fill it with paint, but you can never paint its surface. This "paradox" is known as Gabriel's Horn.
