I must be getting the coordinate system wrong. I want to
calculate something like curl F where
F(x,y,z) = ixz + jyz + ky^2
where i, j and k are the unit vectors in the x, y and z
directions respectively.
<< Calculus`VectorAnalysis`
SetCoordinates[Cartesian[x, y, z ]]
Curl[{xz, yz, -y^2}]
produces
{-2 y, 0, 0}
Yet I would swear it should be -3yi + xj
What am I doing wrong?
