The Extended Tanh Method and the Exp-Function Method to Solve a Kind of Nonlinear Heat Equation

الملخص EN

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.
