The Exact Solution of Fitzhugh–Nagumo Equation by the Variational Iteration Method

In this study, the Variational Iteration Method (VIM) is applied to the Fitzhugh–Nagumo non-linear differential equations. Two case study problems of Fitzhugh–Nagumo are solved by using the VIM and the exact solutions are obtained. The results present capabilities and great potential of the VIM in solving the Fitzhugh–Nagumo equation as a non-linear differential equation.
