You got a long, involved post on Monday. For now, you'll just have to live with learning what I'm doing in math class. Here's the explanation, as best I can give it: "This is the equation to find the volume of a 3-dimensional solid of domain [3π/4, π/4] with a base made of the functions sin3(x) and cos3(x) and cross sections (perpendicular to the x-axis) of a sine wave, with period and amplitude equal to the height of the base at that value x."
Sigh.
