How do you find the equation of a limacon from a graph? FIND THE EQUATION OF LIMACONS CURVE r = a – b cos θ r = a + b cos θ r = a

## How do you find the equation of a limacon from a graph?

FIND THE EQUATION OF LIMACONS CURVE

- r = a – b cos θ
- r = a + b cos θ
- r = a – b sin θ

## How do you write the equation of a limacon?

Equations of the form r = a + b sin θ, a – b sin θ, a + b cos θ, and a – b cos θ will produce limacons. Lets examine what happens for various values of a and b. When the value of a is less than the value of b, the graph is a limacon with and inner loop.

**What is a limacon curve?**

: a plane curve whose equation in polar coordinates has one of the forms ρ = a cos θ ± b or ρ = a sin θ ± b and which reduces to a cardioid when a = b.

### What does a cardioid graph look like?

A cardioid (from Greek, “heart-shaped”) is a mathematically generated shape resembling a valentine heart or half an apple. Constructing a cardioid on a polar graph is done using equations. Imagine if you had a circle of a given radius and you rotate another circle of equal radius around it.

### How do you write an equation for a curved Rose?

Rose curve equations have two forms: r = a cos(nθ) and r = a sin(nθ) where a ≠ 0 and n is a positive integer. Petals have length determined by a. If n is odd, the number of petals is n. However, if n is even, the number of petals is 2n.

**What does a limaçon graph look like?**

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 the 4 different Limacons?

In the image below, for example, the types of limaçon curves are: dimpled, cardioid, and looped (respectively).

#### What does a limaçon 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).
