    Verifying the divergence theorem- half done, help needed

    Homework Statement Verify the divergence theorem for F(x,y,z) = (x,y,2z^2) and T is the region bounded by the paraboloid z=x^2+y^2 and the plane z=1. Homework Equations F(ds) = div(F)dV The Attempt at a Solution I have successfully evaluated the integral and come up with an...

    Triple integral-spherical coordinates

    Hi everyone- thanks for the help so far... tiny-tim, From the pole to the equator, that's pie/2. Is that correct? So I guess in the case that is correct, the limits are as follows: p = from 0 to 3 phi = from 0 to (pie)/2 theta = from 0 to (2pie) Please confirm if I have...

    Triple integral-spherical coordinates

    Homework Statement Here is exactly what the problem says: Let T be a solid of density one that lies below x^2+y^2+z^2=9 and above the XY-plane. a) Use the triple integral to find its mass. b) Find the centroid. Homework Equations I believe that this should be an integral in...
