Abstract: The aim of this paper is to study asymptotic properties of the solutions of the third order delay differential equation \[ \Big (\frac{1}{r(t)}\,y^{\prime }(t)\Big )^{\prime \prime }-p(t)\,y^{\prime }(t)+g(t)\,y\big (\tau (t)\big )= 0\,.\ast \] Using suitable comparison theorem we study properties of Eq. () with help of the oscillation of the second order differential equation.
