Solution of Nonlinear Ordinary Delay Differential Equations Using Variational Approach

The main objective of this paper is to study the variational formulation of nonlinear problems, which may be given in general as a nonlinear ordinary differential equation, nonlinear partial differential equation, nonlinear integral equation , etc. and then introducing the variational formulation of nonlinear ordinary delay differential equations with its solution using the proposed approach given by Tonti.
