An ordinary differential equation (ODE) is an equation Δ(t, f, f′, f″,…, f(N))=0 (1) (with f(j)=dj f/dtj), relating a function f(t) to its derivatives. The order of an ODE is the size of the highest derivative that appears, so...

In mathematics, an ordinary differential equation (or ODE) is a relation that contains functions of only one independent variable, and one or more of its derivatives with respect to that variable. A simple example is Newton's second law of motion, which...
