1polar coordinates A coordinate system in which apoint in the plane is located in terms of its distance r fromthe origin and the angle 0 between the positive x-axis andthe line connecting the point to the origin,measuredcounterclockwise in radians.The polar coordinates of apoint with rectangular...
Coordinates are the two numbers (Cartesian coordinates) or a letter and that point to a specific place on a grid known as a coordinate plane. A coordinate plane has four quadrants and two axes usually represented as x and y axis. The horizontal and vertical distances from the two reference ...
