Exponentially-Fitted Fourth-Derivative Single-Step Obrechkoff Method for Oscillatory/Periodic Problems

The quest for accurate and more efficient methods solving periodic/oscillatory problems is gaining attention in recent time. This paper presents the construction implementation of a family exponentially-fitted Obrechkoff using six-step flowchart discussed literature. A single-step method involving terms up to fourth derivative was used as base method. We also present stability convergence properties constructed methods. Two numerical examples were illustrate performance
