Find the eccentricity of the ellipse if :
the distance between the foci is equal to the length of latus-rectum.

The eccentricity of the ellipse, if the minor axis is equal to the distance between the foci is:

Find the eccentricity of the ellipse if : the latus-rectum is one half of its minor axis.

Find the eccentricity of the ellipse if : the latus-rectum is one half of its major axis.

A parabola is drawn whose focus is one of the foci of the ellipse x^2/a^2 + y^2/b^2 = 1 (where a>b) and whose directrix passes through the other focus and perpendicular to the major axes of the ellipse. Then the eccentricity of the ellipse for which the length of latus-rectum of the ellipse and the parabola are same is

Find the equation of the ellipse refer to its centre whose minor axis is equal to distance between the foci and latus rectum is 10.
