## anonymous 4 years ago divergence theorem anyone?! a conical domain with vertex (0,0,b) and axis along the z-axis has as base a disk of radius a in the xy-plane. find the flux of: F=<x+y^2, 3x^2y+y^3-x^3, z+1> upward through the conical part of the surface of the domain.

found the div F to be 3(x^2+y^2)+2

$b>0\quad\mbox{or}\quad b<0$

b>0; i'm assuming is what's implied. that's all the question asks but it doesn't say (0,0,-b)
