Polar Functions

Definition

Polar functions are mathematical equations that describe curves in terms of a distance from the origin and an angle. They are often used to represent shapes that have radial symmetry.

Analogy

Think of polar functions as GPS coordinates for shapes. Just like latitude and longitude give you a specific location on Earth, polar coordinates give you a specific point on a curve.

Parametric Equations: These are equations that express the coordinates of points on a curve as functions of one or more parameters. They can be used to describe motion or any other situation where multiple variables change simultaneously.

Converting between Cartesian and Polar Coordinates: This refers to the process of converting points from polar form (r, θ) to Cartesian form (x, y), or vice versa. It involves using trigonometry to relate the distance from the origin and angle with x and y coordinates.

Graphing Polar Equations: This is the process of plotting points on a graph using polar coordinates. It involves understanding how changes in radius and angle affect the shape of the curve.
