SUMMARY
Finite difference methods (FDM) and spectral methods are two distinct numerical techniques used for solving differential equations. FDM approximates derivatives by using difference equations, while spectral methods utilize global polynomial approximations based on the function's behavior over the entire domain. The pseudo-spectral method combines aspects of both, leveraging spectral techniques for spatial discretization while applying finite difference methods for time integration.
