Cardioid
- A cardioid is a curve which resembles a heart. Its name is derived from Greek where kardia means heart and eidos means shape, though it is actually shaped more like the outline of the cross section of an apple.
Basic Description
In geometry, a cardioid is the curve traced by a point on the circumference of a circle that rolls around the circumference of another equal circle.
A More Mathematical Explanation
The curve is given by:
- Cartesian equation , where '"`UNIQ--math-00 [...]
The curve is given by:
- Cartesian equation , where is the radius of the moving circle.
- Polar equation
- Parametric equation
