For each of the vector fields below, decide if they have a
nonzero or zero curl at the origin. Each vector field is shown in the
-plane; they have no -component and are independent of .
Note that the vector fields are shown with a dot at the
tail
of each vector.
Vector field
(a) has
curl
at the origin.
Vector field
(b) has
curl
at the origin.
Vector field
(c) has
curl
at the origin.
