Polar Equation

Definition

A polar equation is a mathematical expression that relates the distance and angle of a point in a polar coordinate system. It represents a relationship between the radius (r) and the angle (θ) in polar coordinates.

Polar Coordinate System: A coordinate system where each point is determined by its distance from the origin (represented by r) and its angle from the reference line (represented by θ).

Cartesian Coordinates:

A coordinate system where each point is determined by its position along two perpendicular axes, usually represented as x and y.

Parametric Equations:

Equations that express variables x and y separately as functions of an independent parameter, often denoted as t.
