Question: Let (mathbf{F}) be a vector field whose curl and divergence at the origin are [ operatorname{curl}(mathbf{F})(0,0,0)=langle 2,-1,4angle, quad operatorname{div}(mathbf{F})(0,0,0)=-2 ] Estimate the flux of (mathbf{F})

Let \(\mathbf{F}\) be a vector field whose curl and divergence at the origin are
\[
\operatorname{curl}(\mathbf{F})(0,0,0)=\langle 2,-1,4angle, \quad \operatorname{div}(\mathbf{F})(0,0,0)=-2
\]

Estimate the flux of \(\mathbf{F}\) through the box of side 0.5 in Figure 4 . Does the result depend on how the box is oriented relative to the coordinate axes?
