#### Limacon equation

## What does a Limacon look like?

Limaçon curves look like circles. They have various types depending on the values in their equations. In the image below, for example, the types of limaçon curves are: dimpled, cardioid, and looped (respectively).

## What is polar equation?

Polar Equations A polar equation is any equation that describes a relation between r r r and θ theta θ, where r r r represents the distance from the pole (origin) to a point on a curve, and θ theta θ represents the counterclockwise angle made by a point on a curve, the pole, and the positive x x x-axis.

## What is the meaning of rose in math?

In mathematics, a rose or rhodonea curve is a sinusoid plotted in polar coordinates.

## What is a Limacon graph?

In geometry, a limaçon or limacon /ˈlɪməsɒn/, also known as a limaçon of Pascal, is defined as a roulette formed by the path of a point fixed to a circle when that circle rolls around the outside of a circle of equal radius. A limaçon is a bicircular rational plane algebraic curve of degree 4.

## What are polar coordinates in math?

In mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction. Angles in polar notation are generally expressed in either degrees or radians (2π rad being equal to 360°).

## Why is it called a Limacon?

The name ‘limacon’ comes from the Latin limax meaning ‘a snail’. The limacon is also the catacaustic of a circle when the light rays come from a point a finite (non-zero) distance from the circumference. This was shown by Thomas de St Laurent in 1826.

## What is the difference between a cardioid and a Limacon?

When the value of a is less than the value of b, the graph is a limacon with and inner loop. When the value of a is greater than the value of b, the graph is a dimpled limacon. When the value of a equals the value of b, the graph is a special case of the limacon. It is called a cardioid.
