If t1 and t2 be the parameters of the end points of a focal chord for the parabola y2 = 4ax, then which one is true?
The vertex of the parabola y2 + 6x $$-$$ 2y + 13 = 0 is
The coordinates of a moving point P are (2t2 + 4, 4t + 6). Then its locus will be a/an
The locus of the middle points of all chords of the parabola y2 = 4ax passing through the vertex is
