# Conic Analysis

In the applet below, a conic section is shown.
Recall

**c = distance from center to either focus****a = distance from center to either vertex**## 1.

How would you describe a conic that has c = 0?

## 2.

How would you describe a conic that has c < a ?

## 3.

How would you describe a conic that has c > a ?

## 4.

What happens when c = a ???
