At any given point, more fluid is flowing in than is flowing out, and therefore the “outgoingness” of the field is negative.Yep. 2z, and then minus z squared over 2. You take the derivative, you get negative z. Take the derivative here, you just get 2. So that's right. So this is going to be equal to 2x-- let me do that same color-- it's going to be equal to 2x times-- let me get this right, let me go into that pink color-- 2x times 2z.

It becomes closed again for the terminal range value, but the divergence theorem fails again because the surface is no longer simple, which you can easily check by applying a cut.So the Divergence Theorem for Vfollows from the Divergence Theorem for V1 and V2. Hence we have proved the Divergence Theorem for any region formed by pasting together regions that can be smoothly parameterized by rectangular solids.

The scalar density function can apply to any density for any type of vector, because the basic concept is the same: density is the amount of something (be it mass, energy, number of objects, etc.) per unit of space (area, volume, etc.).
