Abstract. This paper deals with an approximation of a derivative using a dynamic system of the first order. After formulating the problem, two propositions, allowing to find a possible approximation consisting of a dynamic system, are proven. In particular, a proposition based on a Lyapunov approach is proven to show the convergence of the approximation. The second proposition is a constructive one and shows directly the dynamic approximation.
