To demonstrate the validity of the proposed method, the results obtained by HPM have been depicted graphically and have been compared with those of the exact solution. A clear conclusion can draw from the numerical results that the method provides highly accurate solutions to the discussed problem.}, journal = {American Journal of Applied Sciences}, publisher = {Science Publications} }
