Question
Let **F** = \( (x-y, z+y+3, z^2) \) and \( S = \{ (x, y, z) : y = 1 - x^2 - z^2, y \geq 0 \} \) oriented in the positive \( y \)-direction. Compute

\[
\iint_S \mathbf{F} \cdot d\mathbf{S}.
\]

In this problem, we are given a vector field **F** and a surface \( S \) defined implicitly by the equation \( y = 1 - x^2 - z^2 \), with the condition \( y \geq 0 \) ensuring that the surface is above or on the plane \( y = 0 \). The surface is oriented in the positive \( y \)-direction.

The integral is a surface integral of the vector field **F** over the surface \( S \). The operation \( \iint_S \mathbf{F} \cdot d\mathbf{S} \) represents the flux of **F** across the surface \( S \). This type of integral is fundamental in fields such as physics and engineering, where it might represent the flow of a fluid across a surface or the transfer of heat or electricity across a boundary.
