Analytical View of Nonlinear Delay Differential Equations Using Sawi Iterative Scheme

This paper presents the idea of Sawi iterative scheme (SIS) to derive analytical solution nonlinear delay differential equations (DDEqs). We apply transform construct a recurrence relation which is now easy handle and implementation homotopy perturbation method (HPM) reduces components obtain series solution. independent any assumption restriction variables that may ruin actual problem. A transformation keeps consistent known as equation symmetry. It very simple these in presence such symmetries. deal with this approach way results form convergence. also demonstrate graphical show authentic valid for linear problems.
