Abstract
Purpose
This paper aims to show that the variational iteration method (VIM) and the homotopy perturbation method (HPM) are powerful and suitable methods to solve the Fornberg‐Whitham equation.
Design/methodology/approach
Using HPM the explicit exact solution is calculated in the form of a quickly convergent series with easily computable components. Also, by using VIM the analytical results of this equation have been obtained in terms of convergent series with easily computable components.
Findings
Numerical solutions obtained by these methods are compared with the exact solutions, revealing that the obtained solutions are of high accuracy.
Originality/value
Also the results show that the introduced methods are efficient tools for solving the nonlinear partial differential equations.
