For each of the vector field below, decide whether they have a
nonzero curl at the point marked. Each vector field is
shown in the -plane, has no -component and is
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 marked point.
Vector field
(b) has
curl
at the marked point.
Vector field
(c) has
curl
at the marked point.
