The cartesian equation of its directrix is[B]7(iii) The foci of the ellipse + = 1 and the hyperbola–= coincide. Then the value of b2 is[C] 3y = 2(iv)         If the tangent and the normal to x2 – y2 = 4 at a point cut off intercepts a1, a2 on the x-axis and b1, b2 on the y-axis, respectively, then the value of a1a2 + b1b2 is[D]x=0
