Estudo das envolventes de curvas com aplicações no Geogebra

Abstract

In this work we will study several families of plane curves and their envelopes. We present the methods that make it possible to obtain the envelopes for parameterized curves and for equations involving parameters. Two practical applications (cannon firing zone and audibility zone) are also discussed. Didactic activities using the Geogebra software using dynamic geometry resources are presented in the work to obtain the different envelopes.
