Who uses Ellipses?Date: 12/3/95 at 21:3:54 From: Anonymous Subject: ellipses I need to find out who (or what occupation) uses ellipses in their work. There isn't anybody like that I know. Could you help me find one and what they use it on and what it is for? Thank you Date: 7/12/96 at 9:49:46 From: Doctor Alan Subject: Re: ellipses One area where the study of the ellipse is important is astronomy. Ellipses describe the fundamental motion of the planets around a star, such as our planets and the sun. The orbits of planets are not circular, but of an elliptical nature with the sun located at one of the foci. The eccentricity of these ellipses is normally close to unity so they appear as a circle; however, they are ellipses. Comets also follow an elliptical orbit with usually a much higher level of eccentricity. -Doctor Alan, The Math Forum |
