Angular distributions of a \mu ⁺ and a b-quark resulting from the decay of a top quark produced at the e⁺e^- linear collider with unpolarized and 100\% longitudinally polarized electron beam are presented. The results of the standard model are compared with the results obtained in the presence of the anomalous Wtb coupling.
