Modelagem matemática associada a teoria das cores no ensino médio

In the present work we approach linear equation systems, associated to the RGB color system and the use of information technologies, specifically the webcalc website and calculator to solve problems for the teaching of this relevant mathematical topic. The main objective is to provide high school mathematics teachers with a method to present the content in a way that the learning is motivating and meaningful, showing an important application of linear systems. In order to determine the solution of the systems, we used the Gaussian method and the Rouché-Campeli theorem. Finally, a reflection on the results obtained and its relation with the matrix determinant of the coefficients of a linear system and linearly independent vectors of ℝ3. The subjects contemplated in this work were applied in the form of a workshop, using the mathematical modeling in the situations proposed problems, for the students of the State School of Professional Education Professor Walquer Cavalcante Maia
