The Ellipse: A Sum of Distances
Explore the ellipse, defined as the set of points where the sum of the distances to two fixed points (the foci) is constant. We will derive its standard equation and identify its center, vertices, and foci.
About This Topic
Explore the ellipse, defined as the set of points where the sum of the distances to two fixed points (the foci) is constant. We will derive its standard equation and identify its center, vertices, and foci.
Key Questions
- Explain how the two foci define the shape and size of an ellipse.
- Compare the standard equations for ellipses with horizontal and vertical major axes.
- Analyze the equation of an ellipse to find the coordinates of its center, vertices, and foci.
