Abstract
The Laplace transform is one of the most important analytical methods to overcome the difficulties that arise when solving ordinary differential equations or partial nonlinear differential equations. Using the method of Laplace transform reduced the set of partial differtial equations and additional conditions to a set of ordinary differential equations and the corresponding condions . The reduced system can be solved analytically or numerically
