| Nov 1, 2021 at 19:53 | comment | added | user46831 | Thanks Nasser, sadly this proves complicated too because x here is a function of y and I just want the partial evaluated at x[y] not the partial of func[x[y],i,y]. I could get around that with D[func[x,2,y],y]/.x->x[y], but the expressions are complicated and I hope to avoid all that. Hence my use of Derivative. Much appreciated though. | |

Try D[func[x, 2, y], y] which gives 2 + z[2]'[y]
