Question

How do I rotate the area between y=x and y=x^2 around the axis y=x?

Answer 1

1) There is a beautiful way to visualize this: http://www.math.psu.edu/dlittle/java/calculus/index.html
Under "Integral Calculus" > "Solids Generated by Rotation"

Answer 2

Well, thats nice... But I need to know how to rotate the function about the axis y=x. I can do disks and shells for functions rotated about x-axis and y-axis, but not y=x.
