ellipse equation
Hi!
I have to find the equation of an ellipse: i know the foci coordinates, the lenght of the major axis and the length of the minor axis. (Note: the axis are not parallel to the x and y axis of th coordinates system) Can anyone help me? Thank you very much! Francesco Musicman

Set the sum of the two distances equal to the major axis and you have the equation of the ellipse. Simplify. -- RM Mentock I make my protein drink with whiskey -- Arnold
