Polar Coordinates: A coordinate system that uses an angle (θ) and radial distance (r) from a fixed point (origin) to represent points in two-dimensional space.
Polar Graphs: Graphs created using polar coordinates, where points are plotted based on their angle and distance from the origin.
Parametric Equations: A set of equations that express variables x and y independently in terms of another parameter (usually denoted as t), commonly used to represent curves or paths in a plane.
