ABSTRACT
A powerful and effective numerical tool called the Variational Iteration Method has been used to solve various kinds of differential equations over the years. Though the Variational Iteration Method has not been used solely to solve various kinds of differential equations as it has always been coupled with polynomials/transforms. The core of this project is centred on using basically the Variational Iteration Method in solving Delay Differential Equation of First and Second Order. With a very few number of iterations, we obtain an approximated series solution which converges to the exact solution.
