An ellipse is inscribed in a reactangle and the angle between the diagonals of the reactangle is tan^(-1)(2sqrt(2)) , then find the ecentricity of the ellipse

An ellipse is inscribed in a reactangle and the angle between the diagonals of the reactangle is tan^(-1)(2sqrt(2)) , then find the ecentricity of the ellipse

An ellipse is incribed in a rectangle and if the angle between the diagonals is tan ^(-1) 2sqrt2 then e=

An ellipse (x^(2))/(a^(2))+(y^(2))/(b^(2))=1(agtb) is inscribed in a rectangle of dimensilons 2a and 2b respectively, If the angle between the diagonals of the rectangle is tan^(-1)(4sqrt3) , then the eccentricity of that ellipse is

If the angle between the lines joining the end points of minor axis of an ellipse with its foci is pi/2, then the eccentricity of the ellipse is

If alpha, beta are the eccentric angles of the extermities of a focal chord of an ellipse, then eccentricity of the ellipse is
