Tripple integral

  1. Oct 2, 2007 #1
    can someone help me in graphing the following function: x^2+y^2+z^2=z.
    i actually know about x^2+y^2+z^2=k (k=constant) but there above the radius z still changing. the qustion was to intagrate that function and i want to use the spherical coordinates then i will need to know the range of the radius.

    Why dont you complete squares?

    Hint: [itex](z-z/2)^2=z^2-z+1/4[/itex]
