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. WebNov 24, 2024 · Focal Chord: Any chord that passes through the focus of the parabola is called the focal chord. Latus Rectum: A focal chord parallel to the directrix is called the …

WebMar 4, 2024 · I assumed (accidentally and also correctly) that the chord was the diameter, knowing the centre was $(1,2)$ and I found the other vertex as $(2,4)$ and solved the question getting the correct answer. Is there perhaps a generalised method to find the equation of the parabola and the circle? WebThe formula of the centroid thus formed is: ((am 1 2 + am 2 2 + am 3 2) / 3, (2am 1 + 2am 2 + 2am 3) / 3) which is equal to (am 1 2 + am 2 2 + am 3 2) / 3, 0) The tangent present at 1 extremity of a focal chord of a parabola lies parallel to the normal of another extremity. The normal that is other than the axis of the parabola doesn’t pass ... can someone on disability cosign for a house
