Definition

Cartesian Coordinate System

The Cartesian Coordinate System $\mathbb{R}\times \mathbb{R}$ is a plane in ${\mathbb{R}}^3$. Each point is constructed using the cartesian product.

Medians

First Median

The first median is the straight line described by the equation:

$$f(x)=x$$

Second Median

The second median is the straight line described by the equation:

$$f(x)=-x$$

Quadrants

The cartesian coordinate system is divided into four components, called the quadrants:
