An ordinary differential equation (also abbreviated as ODE), in Mathematics, is an equation which consists of one or more functions of one independent variable along with their derivatives. More complicated differential equations can be used to model the relationship between predators and prey. [11] Initial conditions for the Caputo derivatives are expressed in terms of Actually, l would like to try to collect some facts to write a term paper for URJ . {dv\over{dt}}=g.
