WebFind the curl of a 2-D vector field F (x, y) = (cos (x + y), sin (x-y), 0). Plot the vector field as a quiver (velocity) plot and the z-component of its curl as a contour plot. Create the 2-D vector field F (x, y) and find its curl. The curl is a vector with only the z-component. WebTheorem 16.5.1 ∇ ⋅ (∇ × F) = 0 . In words, this says that the divergence of the curl is zero. Theorem 16.5.2 ∇ × (∇f) = 0 . That is, the curl of a gradient is the zero vector. Recalling that gradients are conservative vector fields, this says that the curl of a conservative vector field is the zero vector.

WebThe idea is that when the curl is 0 everywhere, the line integral of the vector field is equal to 0 around any closed loop. Thus, if the vector field is a field of force (gravitational or electric, usually), then the line integral along any path gives us the total work done by the force.
