In this paper, the diffusion equation under square nonlinearity is solved using the WHEP technique, the Homotopy perturbation method (HPM) and Pickard approximation technique. Only the first order approximation is considered with making corrections in the WHEP case. The methods of solution are illustrated through figures, comparisons among different methods and some parametric studies.
