Onumanyi, P.; Fatokun, J.; Adejo, B. O. Accurate numerical differentiation by continuous integrators for ordinary differential equations. (English) Zbl 1153.65068 J. Niger. Math. Soc. 27, 69-90 (2008). Summary: The purpose of this paper is to examine a direct integration of the derivative initial value problem (IVP) for first and second order ordinary differential equations (ODEs). Accurate finite difference approximations are obtained for the derivative function. These are applied in the direct solution of the IVP for the general second order ODEs. Continuous output for \(y\), \(y'\) and \(y''\) is an available option.
