Generic mathematical definitions of the conics

[DivGradCurl]

Hello,

Do you know a website with the most generic mathematical definitions of the conics (parabola, ellipse, hyperbola)?

Thanks

Oh... PERFECT!

I've searched the web for a long time and could not find it. Thank you so much, Tom.

Do you have a reading reference in the web on conics with polar coordinates? I am not sure whether or not there is a real need to switch back to the cartesian form in this particular case.

Thank you very much
