Technical report: solving linear and nonlinear homogeneous diffusion equations by using Homotopy Perturbation Method / Nur Syasya Aznan, Nur Amalina Abd Rasid and Nur Lyiana Najwa Zizi

In this project paper, Homotopy Perturbation Method are applied to solve linear and non­linear diffusion equation. Homotopy Perturbation method have been applied to solved various problem in the past which yield a very accurate solutions. The working of linear and non-linear diffusion equation by using HPM are discussed clearly in order to obtain the analytical results. Comparison is made between results of Homotopy Perturbation Method with the exact solutions to show the accuracy of the results by plotting graphs and computing the errors, thus proved the fact this techniques are very straightforward, simple and effective.
