Polar coordinates
Each point in a plane can be described with polar coordinates, which are indicated by
Explanation
Where r is a positive real number that specifies the distance from the origin. The Greek letter θ (theta) is a real number that specifies the angle with the x-axis.
Polar coordinates are used in the polar notation
x = r · e φ
Example 1
You can convert the rectangular coordinates (x, y) in the polar coordinates (r, θ)
Example 2
You can convert the polar coordinates (r, θ) in the rectangular coordinates (x, y)
