Polar Axis

Definition

The polar axis refers to an imaginary line that passes through both poles (North Pole and South Pole) in polar coordinates. It serves as one reference line for locating points using polar coordinates.

Polar Coordinates: Polar coordinates are a two-dimensional coordinate system that uses an angle and distance from a reference point (usually the origin) to represent points in space.

Polar Angle: The polar angle is the angle formed between the positive x-axis and the line connecting the origin to a point in polar coordinates.

Pole: In polar coordinates, poles refer to the two fixed points (usually represented as North Pole and South Pole) where the polar axis intersects with a plane.
