consider a parabola y^2 = 12x . Now answer the following 1. variable chords of the parabola passing through a fixed point k on the axis, such that some of the reciprocals of the two parts of the chords through k. the coordinate of the point k are 2.all variable chords of the parabola subtending a right angle at the origin are concurrent at the point 3. ab and cd are the chords of the parabola which intersects at a point e on the axis. the radical axis of the two circles describe on ab and cd as diameter always passes through
