The distance from the centre of the ellipse to one of the foci and one of the vertices of the ellipse is called ____________.
Eccentricity
Ellipse
Focal length
None of these
The equation of the parabola with its vertex at (1 , 1) and focus (3 , 1) is
(x - 1)2 = 8 (y - 1)
(y - 1)2 = 8 ( x - 3)
(y - 1)2 = 8 (x - 1)
(x - 3)2 = 8 ( y - 1)
