Abstract

In this paper, a priori error analysis has been investigated for continuous (conforming) Galerkin finite element method used for solving a general scalar linear second-order ordinary BVPs. We derived optimal order a priori error bounds in the  (energy) and  norms utilising the Ritz Projection and standard a priori error analysis techniques and tools.

Keywords: A priori error analysis, finite element methods, ordinary differential equations.
