What does the polar equation $$r = -2$$ represent?

The polar equation $$r = -2$$ represents a circle centered at the origin with a radius of 2.

What type of polar curve is represented by the equation $$r = 2 - 3\text{cos}(\theta)$$ ?

The equation $$r = 2 - 3\text{cos}(\theta)$$ represents an inner loop limacon.

What is the significance of the pole in polar coordinates?

The pole is the origin point in polar coordinates, where the distance r is zero.

What is a spiral of Archimedes?

A spiral of Archimedes is represented by the polar equation $$r = a + b\theta$$ , where a and b are constants, and it spirals outward as θ increases.

What does the polar equation $$r = 1 + \text{cos}(\theta)$$ represent?

The polar equation $$r = 1 + \text{cos}(\theta)$$ represents a cardioid.

How can you identify a dimpled limacon?

A dimpled limacon has a polar equation of the form $$r = a + b\text{cos}(\theta)$$ or $$r = a + b\text{sin}(\theta)$$ , where a

What is the polar equation for a circle centered at the origin?

The polar equation for a circle centered at the origin is $$r = a$$ , where a is the radius.

What is the relationship between polar and Cartesian coordinates?

The relationship is given by the equations $$x = r\text{cos}(\theta)$$ and $$y = r\text{sin}(\theta)$$ .

What type of symmetry does the polar graph $$r = \text{sin}(2\theta)$$ exhibit?

The polar graph $$r = \text{sin}(2\theta)$$ exhibits symmetry about the origin.

What is the polar equation for a line passing through the origin?
