Focal chord
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. WebConsider the parabola x² = 4py and one of its focal chords. Show that the tangent lines to the parabola at the endpoints of the focal chord intersect at right angles.
