A curva catenária como aplicação da função exponencial

Abstract

The current study aims to elaborate a didactic sequence to study the catenary curve through the dynamic geometry perspective. In onder to highlight the importance of using software/application to better understand the function and its graphical representation, a study has been made on its historical development, notation, construction as well as its properties. Therefore, a lesson plan on the curve will be applied to High School students. Based on their reports, we intend to analyze and discuss these results.
