Let A be the potential function of $F(x,y,z)=(4xy+z^2)i+(2x^2+6yz)j+(2xz+3y^2)k$ evaluated at the point $(-1,-2,-3).$

Let $B={\displaystyle \underset{C}{\overset{\phantom{}}{}}}F*dr$ for $F(x,y,z)=$xyi$+xzj+yzk$;$C$:$r(t)=ti+t^{2}j+2tk$;$0t2$

Given: $F(x,y,z)=3+7yj+3zk$ and $G(x,y,z)=-7yi-7$zj $-5$xk

Let $C=$div$(FG)$ at the point $(-\frac{1}{7},\frac{1}{7},\frac{1}{3}).$
