Polar coordinates are a system of locating points on a plane using a distance from the origin and an angle from a reference axis.
To travel clockwise from (0,-1) to (0,1) in polar coordinates, you would start at the point (0,-1) and move in a circular motion around the origin until you reach the point (0,1). This would involve increasing the angle while keeping the distance from the origin constant.
The reference axis in polar coordinates is a fixed line passing through the origin and used as a starting point for measuring angles.
The distance from the origin in polar coordinates is known as the radius and is measured in units such as meters or feet.
Yes, polar coordinates can be extended to three dimensions by adding a third coordinate, known as the z-coordinate. This allows for the location of points in a three-dimensional space using a distance, angle, and height from the origin.
