An ellipse can be formed in several ways, here are two examples:
- A circle viewed from an angle looks like an ellipse.
- While a circle is a horisontal cut through a cone, an ellipse can be taken from a cone with an angular cut.
Now, assume that a point moves around the circle at constant speed. What speed will the same point have on an ellipse which has the relationship to the circle as described above (for example, it is the circular movement viewed from an angle)?
Let's think about speed as angular speed relative to the center of the ellipse.
