- If (2, 0) is the vertex and y-axis the directrix of a parabola, then find its focus.
- If the parabola y2 = 4x passes through (–3, 2), then find length of its latus rectum.
- Find the ends of latus rectum of parabola x2 + 8y = 0.
- Find the equation of the lines joining the vertex of the parabola y2 = 6x to the points on it whose abscissa is 24.
- Find the points on the parabola y2 = 36x whose ordinate is three times the abscissa.
- Find the co-ordinates of the extremities of the latus rectum of the parabola 5y2 = 4x.
