Eccentricity of an ellipse?

Postby Celsion » Fri Mar 30, 2007 12:29 am

What's the equation for finding the eccentricity of an ellipse? Also, how can you tell if a polynomial is an ellipse, circle, parabola, hyperbola, and etc? [unparseable or potentially dangerous latex formula] or something like that.

Looks like you want to learn about conic sections: http://en.wikipedia.org/wiki/Conic_sections

Definitely worth the read, as it will tell you other properties that are often queried about conic sections.
