By imposing different conditions on nonlinearity, we establish various of existence results. Besides, some results generalize Jiang [5] for ordinary differential equations. In particular, nonlinearity involving the first derivative of x is considered.&lt;/p&gt;

Main results are besed on fixed point theorem on cone. In particular, the nonlinear term is involved with the first-order derivative.&lt;/p&gt;
