WebIf Z{f n} = F(z), then Z{f n–k} = z-k F(z). (5) Initial value Theorem . Proof . We know that F (z) = f 0 + f 1 z-1 + f 2 z-2 + . . . Taking limits as z ® ... WebIf z and w are reciprocals, then zw = 1, so the product of their absolute values is 1, and the sum of their arguments (angles) is 0. This means the length of 1/ z is the reciprocal of the length of z. For example, if z = 2, as in the diagram, then 1/ z = 1/2. It also means the argument for 1/ z is the negation of that for z.
