The types of computer graphics and their application at different levels of knowledge

In this article we introduce the concept of computer graphics and graphical application C.a.R (Compasses and Ruler), its basic commands and several examples associated with the geometry. This subject is at all levels of knowledge in various stages of development. We will present the C.a.R possibilities that can be used in secondary schools, high schools and colleges. We show function graphs of varying degrees of difficulty that are too complicated for the human imagination.
