spring–mass systemmathematical modelingbounded forcingpolynomial driversunbounded forcingGreen's functionHow should our students think about external forcing in differential equations setting, and how can we help them gain intuition? To address this question, we share a variety of problems and projects ...

5.11 Higher-Order Differential Equations Higher-order differential equations contain differential terms of second order or above, for example, the third-order differential term d3y/dx3. Higher-order differential equations can be solved by converting them to a system of first-order differential equation...
Mathematical modeling of the mass-spring-magnetorheological damper mechanical system has been presented here. The main focus of the investigation is to show how the fractional order γ changes by varying the viscosity damping coefficient β. These observations have been made by varying current intensity...
