The foci of an ellipse are S(-1,-1), S'(0,-2) its e=1/2 , then the equation of the directrix corresponding to the focus S is

The foci of an ellipse are S(-1,-1), S'(0,-2) its e=1/2, then the equation of the directrix corresponding to the focus S is

Find the equation of the hyperbola whose one focus is (-1, 1) , eccentricity = 3 and the equation of the corresponding directrix is x - y + 3 = 0 .

Find the equation of the hyperbola whose one focus is (-1, 1) , eccentricity = 3 and the equation of the corresponding directrix is x - y + 3 = 0 .

A parabola with focus S=(1,2) touches both the axes then the equation to directrix is

The locus of the foot of perpendicular from my focus of a hyperbola upon any tangent to the hyperbola is the auxiliary circle of the hyperbola. Consider the foci of a hyperbola as (-3, -2) and (5,6) and the foot of perpendicular from the focus (5, 6) upon a tangent to the hyperbola as (2, 5). The directrix of the hyperbola corresponding to the focus (5, 6) is
