Hello Jerry, Practically, there is no difference to the user---so it is a matter of choice, but is does serve to reiterate the maxim "everything is an expression." There are times when the form of the function may reflect your thinking about it: here is a trivial example: myBesselJ[i_][z_] := BesselJ[i,z] bessels[n_,y_] := Sum[myBessel[i][y],{i,1,n}] On Wed, Jun 4, 2008 at 5:37 AM, Jerry <Jer75811 at yahoo.com> wrote: > Sir, I have never seen a function definition in the form you > give: > f[a_][x_] := x (a + Log[x])^2 > > After a bit of playing with it, I don't see the difference > between this and > > f[a_,x_] := x (a + Log[x])^2 >
