tives. This is achieved by a suitable de nition. The de nition of the functional derivative (also called variational derivative) is dF [f + ] d =0 =: dx 1 F [f] f(x 1) (x 1) . (A.15) This de nition implies that the left-hand side can be brought into the form on the right-hand side, i.e. the form of a linear functional with kernel F [f]/ f acting on

To nd the derivative of fat 0, we need to use the de nition: f0(0) = lim h!0 j0 + hjj 0j h = lim h!0 jhj h From previous examples we already knew that this limit does not exist, since lim h!0 jhj h = 1 while lim h!0+ jhj h = 1. If we look at the graph of the jxjfunction we see that there’s a sharp corner at x= 0. E.g. f(x) = 3 p xis non-di ...
