If the angle between the lines joining the Foci to an extremity of minor axis of an ellipse is "`90^(@).`" Its eccentricity is '`e`' then "`8e^(2)`" is "]

If the angle between the lines joining the foce of any ellipse to an extremity of the minor axis is 90^0 , find the accentricity. Find also the equation of the ellipse if the major axis is 2sqrt(2) .

If the angle between the lines joining the foci of any ellipse to an extremity of the minor axis is 90^0 , find the eccentricity. Also find the equation of the ellipse if the major axis is 2sqrt(2) .

If the line joining foci subtends an angle of 90^(@) at an extremity of minor axis, then the eccentricity e is

If the lines joining the foci of an ellipse to an end of its minor axis are at right angles , then the eccentricity of the ellipse is e =

In the ellipse distance between the foci is equal to the distance between a focus and one end of minor axis then its eccentricity is

If the angle between the straight lines joining foci and the ends of minor axis of the ellipse (x^(2))/(a^(2))+(y^(2))/(b^(2))=1 is (pi)/(2) then the eccentricity is

In an ellipse,if the lines joining focus to the extremities of the minor axis form an equilateral triangle with the minor axis,then the eccentricity of the ellipse is
