Focal chord of parabola formula

WebNote: If the chord joining the points t1 and t2 on the parabola y2 = 4ax is a focal chord then t1t2 = –1. Proof: Equation of the parabola is y2 = 4ax Focus S = (a, o) The equation of the chord is y(t1 + t2) = 2x + 2at1t2 If this is a focal chord then it passes through the focus (a, 0). ∴ 0 = 2a + 2at1t2 ⇒ t1t2 = –1.
