Under oscillation criteria, some equations are then selected. Exploring the numerical solution of corresponding dynamic system individually on different time scales not only visualizes the oscillating motion as theoretically expected but also reveals other interesting behavior patterns. This study finally suggests that a time domain also plays an important role on the boundedness of oscillatory solution. © Dynamic Publishers Inc.Mahidol UniversityComputer ScienceMathematicsArticleSCOPUS
