Abstract: In this study, we shall study the radial oscillation of solutions of n-th order complex linear differential equations f (n) A (z)n-1 f(n-1)+...+ A1 (z) f’+A0 (z)f = F (z) where, Aj(z), j = 0, 1, ..., n-1 and F(z) are transcendental entire functions. We shall add some conditions on coefficients which show the relation between the Borel directions of solutions f and that of F(z), further we obtain some estimates of growth of solutions in the angular domains.
