    Abstract: This paper presents a direct approach for numerical solution of special second order delay differential equations (DDEs) directly without reduction to systems of low orders. The methods were generated using collocation approach via a combination of power series and exponential function. The approximate basis functions are interpolated at the first ... Show More
