Which of the following options is the primary purpose of a polar coordinate system? the primary purpose of a polar coordinate system is to create ordered pairs. the primary purpose of a polar coordinate system is to tell x and y locations. the primary purpose of a polar coordinate system is to determine the position of a point. the primary purpose of a polar coordinate system is to calculate lengths and angles between points.

The primary purpose of a polar coordinate system is to calculate lengths and angles between points

Step-by-step explanation:

Hello

A polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction,Polar coordinates are best used when periodic functions are considered,in fact, describing position is therefore far more natural than using two distances on a grid

I hope it helps.
