%0 Journal Article %T Boundedness and Asymptotic Behaviour of Solutions of a Second Order Nonlinear Differential Equation %A Maher Nazmi Qarawani %J Journal of Mathematics Research %D 2012 %I %R 10.5539/jmr.v4n3p121 %X This paper considers asymptotic behaviour of solutions of a nonlinear differential equation of second order where the coefficient of nonlinearity is a bounded function for arbitrarily large values of $x$ in $mathbb{R}$. Here we obtained sufficient conditions for boundedness, convergence of solutions to zero as $x ightarrowinfty$, and unboundedness of solutions. %U http://www.ccsenet.org/journal/index.php/jmr/article/view/16225
