WebFocal Chord: The focal chord of a parabola is the chord passing through the focus of the parabola. There are two points of intersection on the focal chord. Focal Distance: The distance of a point on the parabola, from the focus, is the focal distance. Also, the focal distance is equal to the perpendicular distance of this point to the directrix. WebThe minimum length for any focal chord is evidently obtained when t =±1, t = ± 1, which gives us the LR. Thus, the smallest focal chord in any parabola is its LR. Example – 8.

WebSep 29, 2024 · Find the equation of the focal chord of the ellipse 3 x 2 + 4 y 2 = 48 , whose length is 7. I found that one of the foci of the ellipse is (2; 0). If I express the equation of the line L that is requested as L: y = mx + b, and replace the coordinates of the point (2; 0), I obtain b = -2m. With this we have L: y = m (x-2). WebIf we take the points P and Q to be the parametric points c and d on the parabola then we have the length of the chord to be: Length = PS + QS = a + a + ac 2 + ad 2 = 2a + a(c 2 +d 2) We need the value of (c 2 + d 2) Since: cd = -1. c + d = -1 (from (1)) (c + d) 2 = c 2 + d 2 + 2cd. 1 = c 2 + d 2-2. c 2 + d 2 = 3 => Thus length = 5a.
