Section 7.3 The Ellipse

OBJECTIVE 1

Find an equation of the ellipse with center at the origin, one focus at (0, – 3) and a vertex at (5, 0). Graph the equation.

Find an equation of the ellipse having one focus at (0, 2) and vertices at (0, – 5) and (0, 5). Graph the equation by hand.

OBJECTIVE 2

Find an equation for the ellipse with center at (– 2, 4), one focus at (3, 4), and one vertex at (– 7, 4). Graph the equation by hand.

OBJECTIVE 3

The whispering gallery in the Museum of Science and Industry in Chicago is 47.3 feet long. The distance from the center of the room to the foci is 20.3 feet. Find an equation that describes the shape of the room. How high is the room at its center?
