Abstract: Different from the traditional study of time-invariant problems, in this paper, the more complex hybrid time-dependent linear-nonlinear dynamic system (HTDLNDS) is studied, that not only has ...

A direct power series substitution technique is proposed to solve second order nonlinear differential equations. The errors in truncated power series are estimated to determine the significance of the ...

Abstract: Differential equation is a useful way to describe nonlinear systems. In general, integration is used to solve them, which is a forward method using current information to get the future ...
