Gauss's law does not mention divergence. The divergence theorem was derived by many people, perhaps including Gauss. I don't think it is appropriate to link only his name with it.

V.By the divergence theorem, the flux is zero. 4 Similarly as Green’s theorem allowed to calculate the area of a region by passing along the boundary, the volume of a region can be computed as a flux integral: Take for example the vector field F~(x,y,z) = hx,0,0i which has divergence 1. The flux of this vector field through Divergence and curl are not the same. (The following assumes we are talking about 2D.) Curl is a line integral and divergence is a flux integral.

Example 1-6: The Divergence Theorem; If we measure the total mass of fluid entering the volume in Figure 1-13 and find it to be less than the mass leaving, we know that there must be an additional source of fluid within the pipe. If the mass leaving is less than that entering, thenThe divergence of a vector field simply measures how much the flow is expanding at a given point. It does not indicate in which direction the expansion is occuring. Hence (in contrast to the curl of a vector field ), the divergence is a scalar.

Via Gauss's theorem (also known as the divergence theorem), we can relate the flux of any vector field F~ through a closed surface S to the integral of the divergence of F~ over the volume enclosed by S: I S F~ ·dA~ = Z V divF dV .~Since Δ Vi – 0, therefore Σ Δ Vi becomes integral over volume V. Which is the Gauss divergence theorem. According to the Gauss Divergence Theorem, the surface integral of a vector field A over a closed surface is equal to the volume integral of the divergence of a vector field A over the volume (V) enclosed by the closed surface.You are correct that P could increase if P (x,y) = 2y. However, it would not increase with a change in the x-input. Thus, the divergence in the x-direction would be equal to zero if P (x,y) = 2y. In this example, we are only trying to find out what the divergence is in the x-direction so it is not helpful to know what partial P with respect to ...generalisations of the fundamental theorem of calculus to these vector spaces.
