What is curl of a vector field. That is why the divergence of curl of $\vec{F}$ must be zero. The gradient of a scalar field points into the direction of the strongest change of the field. So it is perpendicular to isosurfaces of the scalar field and that already requires that the curl of the gradient field is zero. A good example to visualize is a temperature distribution.

What is curl of a vector field. Identify the field With line integrals, we must have a vector field. You must identify this vector field. Compute the scalar curl of the field If the scalar curl is zero, then the field is a gradient field. If the scalar curl is “simple” then proceed on, and you might want to use Green’s Theorem.
