The Variational Iteration Method for the Newell-Whitehead-Segel Equation

The Variational Iteration Method (VIM) is used to solve the Newell-Whitehead-Segel non-linear differential equations. Three case study problems of Newell-Whitehead-Segel are solved by using the VIM and the exact solutions are obtained. The capability and great potential of the VIM in solving the non-linear differential equations is also proved by applying the method to the Newell-Whitehead-Segel equation.
