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

Distance between foci = 10 and eccentricity = 3/2

Distance between foci is 6 and eccentricity is 3/5

The distance between the directrices fo an ellipse is four times the distance between their foci. Then the ecentricity fo the ellipse is

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