Dear Users,

 

I have a function 

 

                Norton[arg_,exp_,nenner_]:= MCB[arg / nenner]^exp

 

I want to define my own deviation of the function Norton,
D[Norton[arg,exp,nen],y[1]]:=dNdx[arg,exp,nen]

arg depends on y[1].

I have tried it with

 

                Derivative[1,0,0][Norton][arg_,n_,k_]:=dNdx[arg,n,k]

 

But I get an error.

 

Thanks in advance.
