If the angle between asymptotes is 30 then find its eccentricity

If the angle between the asymptotes is 30^(@) then find its eccentricity.

If the angle between the asymptotes is 30^(@) then find its eccentricity.

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 e is the eccentricity of (x^(2))/(a^(2))-(y^(2))/(b^(2))=1 & theta be the angle between the asymptotes, then sec theta//2 equals

The angle between the asymptotes of the hyperbola S=0 is

If the eccentricity of a hyperbola is 2, then find the eccentricity of its conjugate hyperbola.

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