Hello John,

You put x and z too close, without a space between them.
It is good way to say Derive you want multiply x by z.

However, for Mathematica xz means a SINGLE variable.


        << Calculus`VectorAnalysis`SetCoordinates[Cartesian[x, y, z]];

        Curl[{xz, yz, -y^2}]

        {-2 y, 0, 0}

        Curl[{x z, y z, -y^2}]

        {-3 y, x, 0}
