PSQ is a focal chord of the parabola y^2=8x. If\ S P=6, then write SQ.

If PQ is a focal chord of parabola y^(2) = 4ax whose vertex is A , then product of slopes of AP and AQ is

P is any point on the parabola, y^2=4ax whose vertex is A. PA is produced to meet the directrix in D & M is the foot of the perpendicular from P on the directrix. The angle subtended by MD at the focus is: (A) pi/4 (B) pi/3 (C) (5pi)/12 (D) pi/2

A point on the parabola whose focus is S (1,-1) ans whose vertex is A(1,1) is
