Hello guys.

How to determine the gradient of the following vector field below:

with(VectorCalculus):

with(Student[VectorCalculus]):

SetCoordinates('cylindrical'[r, theta, z]):

V:=VectorField(<omega*r, 0, z*r>)

Gradient(V, [r, theta, z]);

Error, invalid input: too many and/or wrong type of arguments passed to Student:-VectorCalculus:-Gradient; first unused argument is Vector(3, [omega*r,0,z*r], attributes = [vectorfield, coords = cylindrical[r,theta,z]])
