This paper presents some finite difference methods for solving initial-boundary value problems in partial differential equations namely explicit method, implicit method and Crank Nicolson method. Finite difference methods are used to solve partial differential equations by approximating the differential equations over the area of integration by a system of algebraic equations. We discuss the convergence of these methods in the context of the exact solution. Moreover Crank Nicolson method is unconditionally stable, more accurate and converges faster than its two counterparts, the explicit and implicit methods.
Keywords: Accuracy, Convergence, Crank Nicolson Method, Finite Difference Method, Explicit Method, Implicit Method.
