Focal point of parabola formula
WebThe given focus of the parabola is (a, 0) = (4, 0)., and a = 4. For the parabola having the x-axis as the axis and the origin as the vertex, the equation of the parabola is y 2 = 4ax. Hence the equation of the parabola is y 2 = 4 (4)x, or y 2 = 16x. Therefore, the … WebJul 3, 2024 · Focus: Focus is the fixed point of a parabola. Directrix: The directrix of a parabola is the line perpendicular to the axis of a parabola. Focal Chord: The chord that passes through the focus of a parabola, cutting the parabola at two distinct points, is called the focal chord. Focal Distance: The focal distance is the distance of a point (x 1, y 1) …
