AbstractIn engineering careers, the study of the Differential and Integral Calculus begins in the first course of Calculus. In order to understand the definitions and theorems involving such contents, students need to handle symbolic and graphical representations. With GeoGebra, it is possible to create different interactive applications that can be used as teaching tools to illustrate math classes. In this paper, some animations of the fundamental concepts of Calculus are shown, emphasizing the analysis of their geometric interpretations. These tools were designed for the Calculus I course at the Facultad Regional San Nicolás, Universidad Tecnológica Nacional, Argentina.
