WebSep 25, 2024 · I solved it using the parametric form of parabola and got the answer. But then when I tried using geometry, I'm stuck, in the figure A1B1 is a focal chord, and A2 is a point on parabola, A2A1 intersects directrix at O. Then B2 is the intersection of A1F and B1O,B2' is foot of perp of B2 on directrix.
