Hi Aaron, the partial differential operator is: Derivative. In your case qwe would wrote: g=Derivative[0,1,0][f] hope this helps, Daniel Aaron Fude wrote: > Hi, > > Suppose I have a function of three variables > > f[x_, y_, z_]:=Sin[x y z] > > And I want to construct g[x, y, z] which is the partial derivative of f > [] with respect to y.
