EQUAGRAF: Una aplicació per aprendre a resoldre sistemes d'equacions a través d'un graf

Abstract

This project is a web application that can solve systems of first order equations and graphically shows the procedure by developing a graph. The main function of this app is help the user to understand what are the steps to be performed to solve his system of equations. In order to run the application, the user has to enter the different equations of his system and also has to indicate the inputs (variable values) and the outputs (variables to find). Once all the data is known, the program will show the graph with all the different steps and the final result (outputs) will be displayed on the screen. During the learning how to solve a system of equations the teachers have taught us how to solve the systems through the methods of inspection, elimination, substitution and Gauss. Those methods are based on the resolution of systems of equations through repeat performing various similar problems. The main goal of this web application is solving systems of first order equations ensuring that the user internalizes each step of the resolution. Because that, this app shows different graphs that will help the user to understand the process of finding the solution through the methods of elimination and inspection. This project is focused on several target audiences. This app can help students that are learning for the first time to solve a system of equations, and also more advanced students that in his physics or economics problems may have to solve systems of equations with a lot of outputs.
