θ is the symbol used to represent an angle in polar coordinates. It measures the rotation from the positive x-axis to a point in the coordinate plane.
A system that uses an angle (θ) and distance (r) to locate points in a plane.
A curve defined by equations involving θ and r, where r represents the distance from the origin and θ represents the angle.
Polar Graphing: The process of plotting points on a graph using polar coordinates instead of Cartesian coordinates.
