In this paper, we develop a method to obtain
approximate solution of nonlinear heat equation with the help
of Laplace Decomposition Method (LDM). The technique is
based on the application of Laplace transform to nonlinear
partial differential equation. The nonlinear term can easily be
handle with the help of Adomian polynomials. We illustrate
this technique with the help of three examples and results of
the present technique have closed arrestment with
approximate solutions obtained with the help of Adomian
Decomposition Method (ADM).
