Find the (i) lengths of the axes, (ii) coordinates of the vertices, (iii) coordinates of the foci, (iv) eccentricity and (v) length of the rectum of each of the following the hyperbola :

3y2 – x2 = 108


Given Equation: 3y2 – x2 = 108


Comparing with the equation of hyperbola we get,


a = 6 and b =



(i) Length of Transverse axis = 2a = 12 units.


Length of Conjugate axis = 2b = units.


(ii) Coordinates of the vertices = (0, a) = (0, 6)


(iv) Here, eccentricity, e =


(iii) Coordinates of the foci = (0, ae) = (0, 12)


(v) Length of the rectum = units.
