The extended tanh method and the exp-function method to solve a kind of nonlinear heat equation

Abstract

We study a kind of nonlinear heat equation with temperature-dependent thermal properties by the aid of the extended Tanh method and the Exp-function method. We obtain abundant new exact solutions of the equation. By comparing both of the methods, we find that the Exp-function method gives more solutions in this problem. Copyright © 2010 Weimin Zhang.
