PX275 - E2a - divergence theorem

\underset{flux flowing out of a loop}{\underset{⏟}{\oint_{C} \vec{F} \cdot d \vec{r}}} = \underset{divergence integrated over area R}{\underset{⏟}{\iint_{R} \vec{\nabla} \cdot \vec{F} d A}}

\iint_{S} \vec{F} \cdot d \vec{s} = ∭_{V} (\vec{\nabla} \cdot \vec{F}) d V
