The purpose of this research is to explore the use of an interactive learning object (ILO) with the aim to improve the teaching of Differential Calculus and Cost curses. This is realized through an interactive object in the free software GeoGebra with the purposes of facilitating the teaching and learning processes in differential calculus and the appreciation of the applied and practical utility in this and others knowledge field by students. The relevant contribution of this paper are the generation of a tool for teachers and students where the can develop work outside of class, create new questions and have a good appropriation of the acquired theoreti cal knowledges in class through the heuristic interactions between teachers, students and the ILO.
