Equations 29b, 30b and 31b indicate that when the angular difference lies in a closed interval [-G, G], there always exists a variable Ub such that equations 30b and 31b hold. That is to say, if the value of G is large enough, equations 29b, 30b and 31b put no restriction on the angular variables. ................
