Study Notes
Polar Coordinate System
- The reference point in the polar coordinate system is called the pole.
- The distance from the pole is called the radius or radial distance.
History
- The concept of polar coordinates was introduced by Gregoire de Saint-Vincent in the mid-17th century.
Applicability
- Polar coordinates are most appropriate in contexts where there is a natural center or origin, such as navigation, physics, engineering, and astronomy.
Notation
- Angles in polar notation are generally expressed in radians or degrees, usually counterclockwise from the positive x-axis.
