Introduction to Cartesian Geometry and Cartesianization of Complex Shapes

摘要

The Cartesian word or "Cartesianity" was born with the philosophy of Descart (1596 - 1650). He was at the base of a doctrine based on rationalism, that it is means the search for truth by reason. Among others, Sigmend Freud had also approached this notion of psychological point to study the enigma of thoughts in humans. Other aspects of the Cartesian word have been used in mathematical geometry, namely cartesian coordinates and Cartesian referentials. As you know, studying a shape with curved and enclosed borders is more complicated than working on shapes with linear borders without curvature. In the way, we will introduce to the Cartesian geometry and characterize he Cartesian shapes.
