19. Use of Laplace Transforms in Solving PDEs
Laplace Transforms provide a powerful method for solving linear partial differential equations (PDEs), particularly in scenarios involving time-dependent processes by transforming them into ordinary differential equations (ODEs). The method simplifies the resolution of complex PDEs, allowing for efficient retrieval of solutions through inverse transforms. This technique is instrumental across various applications in physics and engineering, including heat conduction, wave propagation, and fluid dynamics.
