Finite Elements and Finite Differences in some differential equations of second linear order with GeoGebra

Abstract

Abstract In this paper we will show the numerical solutions of some linear second order differential equations through the finite difference methods with Lagrange interpolation and finite elements, using GeoGebra software. These numerical solutions mediated by GeoGebra are visualized with dynamic applets, which were built to analyze the absolute error produced by the corresponding solution and the approximation and also as an interactive teaching support material for the course of Numerical Calculation for Engineering and Science students.
