cardioid

Enlarge picture
The cardioid is the curve formed when one circle rolls around the edge of another circle of the same size. It is named after its heart shape.

Heart-shaped curve traced out by a point on the circumference of a circle, resulting from the circle rolling around the edge of another circle of the same diameter.

The polar equation of the cardioid is of the form:

r = a(1 + cos θ) where the polar coordinates of the point are (r, θ) and a is a constant.
