Application

Problem: A big room is constructed so that the ceiling is a dome that is semielliptical In shape. If a person stands at one focus and speaks, the sound that is made bounces off the ceiling and gets reflected to the other focus. Thus, if two people stand at the foci (ignoring their heights), they will be able to hear each other. See figure below. Assume that it was complete ellipse, give the center, vertices, covertices as well as the lengths of the major and minor axes. IT Center Vertices Covertices Length of Major Axis Length of Minor Axis
