AB is double ordinate of the hyperbola `x^2/a^2-y^2/b^2=1` such that `DeltaAOB`(where 'O' is the origin) is an equilateral triangle, then the eccentricity e of hyperbola satisfies:

AB is double ordinate of the hyperbola (x^(2))/(a^(2))-(y^(2))/(b^(2))=1 such that Delta AOB( where 'O' is the origin) is an equilateral triangle,then the eccentricity e of hyperbola satisfies:

If PQ is a double ordinate of the hyperbola (x^(2))/(a^(2))-(y^(2))/(b^(2))=1 such that OPQ is an equilateral triangle,O being the center of the hyperbola, then find the range of the eccentricity e of the hyperbola.

If PQ is a double ordinate of the hyperbola such that OPQ is an equilateral triangle, being the centre of the hyperbola, then eccentricity e of the hyperbola satisfies

Find the eccentricity of hyperbola x^(2)-9y^(2)=1 .

The eccentricity of the hyperbola 3x^(2)-4y^(2)=-12 is

Eccentricity of the hyperbola x^(2) - y^(2) = a^(2) is :
