Homework Statement
g(x,y,z) = z2; Ʃ is the part of the cone z = [itex]\sqrt{x2+y2}[/itex] between the planes z = 1 and z = 3.
Homework Equations
Conversion to polar coordinates
∫∫Ʃg(x,y,z)dS = ∫∫Rg(x,y,f(x,y)) [itex]\sqrt{fx2 + fy2+1}[/itex]
The Attempt at a Solution
If we're talking in terms of r and θ, r goes from 1 to 3 and θ goes from 0 to 2π. I converted to polar coordinates from cartesian and I got 8*π*√2 *z2. If you were converting to polar/cylindrical coordinates, z2 wouldn't change, correct?
Sorry, for some reason the square root LaTeX command didn't want to work...
