A polar function is a type of mathematical function that describes points in a plane using polar coordinates, which consists of a distance from the origin (r) and an angle from the positive x-axis (θ).
A system for locating points in a plane using an ordered pair (r, θ), where r represents the distance from the origin and θ represents the angle.
Polar Graph: A graph that represents a polar function by plotting points with their corresponding polar coordinates.
An equation that defines a relationship between r and θ, which determines how points are plotted in a polar graph.
