Abstract
The aim of this paper is to compute the numerical
solution of special second order delay differential equations directly by a
four-step multi-hybrid block method. The methods were generated using
collocation and interpolation approach by means of a combination of power
series and exponential function at some selected grid and off-grid points. The
developed schemes and its first derivatives was combined to form block methods
to concurrently solve special second order delay differential equations
directly without reducing it to the system of first order. The basic properties
of the methods such as order, error constants, consistency and convergence were
examined. The developed methods were applied to solve some second order delay
differential equations, the methods also solve application problem in other to
test for the efficiency and accuracy of the methods. The results are displays
in the tables.
