A possible source of confusion is the inclusion of something in the variable list that was intended to be a constant parameter, such as c in cxyz. In this case, c will be interpreted as a variable, and you will obtain a 4×4 matrix. Since c occurs first in the alphabet, partial derivatives involving c occur in the first row and column. Delete the first row and first column of the resulting matrix to get the desired result.

After defining f (x, y, z) = 3xy2z, you can find the Hessian for the expression f (x, y, z).
