If (distance between directrices ) = 3 (distance between foci) , then e =

If distance between foci = 3 (distance between directrices) . Then e =

Find the eccentricity of the ellipse (a lt b) if the distance between the directrices is 5 and distance between the foci = 4.

If the distance between the directrices is thrice the distance between the foci, then find eccentricity of the ellipse.

If the distance between the directrices is thrice the distance between the foci, then find eccentricity of the ellipse.

If the distance between the directrices is thrice the distance between the foci, then find eccentricity of the ellipse.

If the distance between the directrices is thrice the distance between the foci, then find eccentricity of the ellipse.

If the distance between the directrices is thrice the distance between the foci, then find eccentricity of the ellipse.

In an ellipse (x^(2))/(a^(2))+(y^(2))/(b^(2))=1 if the distance between the directrix is 3 times the distance between the foci, then the eccentricity is

e = 3/2 and distance between directrices = 8/3

In an ellipse, the distance between its directrices is four times the distance between its foci. If (-2, 0) is one of its vertices, then the equation of the ellipse is
