SUMMARY

The discussion focuses on applying Gauss's Theorem to maximize the flux of the vector field F(x,y,z) = (16x - xz^2)i - (y^3)j - (zx^2)k. The divergence of F is calculated as divF = 16 - z^2 - 3y^2 - x^2, which must be greater than zero to define the volume of interest. Participants are tasked with identifying the closed surface that bounds this volume, emphasizing the relationship between divergence and surface area in the context of maximizing flux.

Homework Statement



Use the Divergence (Gauss's Theorem) to find the outward oriented closed surface (no boundary) for which the flux of F(x,y,z) = (16x-xz^2)i-(y^3)j-(zx^2)k is maximized.

The Attempt at a Solution


divF = 16-z^2-3y^2-x^2 > 0 I think ?

Yes. But 16-z^2-3y^2-x^2 > 0 describes a volume. What's the surface that bounds that volume?
