The distance between the directrices of the hyperabola x=8 sec theta, y =8 tan theta is-

Write the distance between the directrices of the hyperbola x=8s e ctheta,\ y=8t a nthetadot

If the distance between foci of a hyperbola is twice the distance between its directrices, then the eccentricity of conjugate hyperbola is :

If the distance between foci of a hyperbola is twice the distance between its directrices, then the eccentricity of conjugate hyperbola is :

Find the equation of the hyperbola, referred to its principal axes as axes of coordinates in the following cases: a. The distance between the foci =16 and eccentricity =sqrt(2) b. Conjugate axis is 5 and the distance between foci =3 c. Conjugate axis is 7 and passes through the point (3,-2).
