WebNote that: (i) Perpendicular distance from focus on directrix = half the latus rectum. (ii) Vertex is middle point of the focus & the point of intersection of directrix & axis. (iii) Two parabolas are laid to be equal if they have the same latus rectum. ... FOCAL PROPERTY : The difference of the focal distances of any point on the hyperbola is ... WebSolution: The directrix of parabola is x + 5 = 0. The focus of the parabola is (a, 0) = (5, 0). 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 (5)x, or y 2 = 20x. Therefore, the equation of the parabola is y 2 = 20x. how to make your own recycled paper

WebJul 17, 2024 · The reflection of the focus F in the tangent at P is specifically the projection (say, P ′) of P onto the directrix. This is effectively the reflection property of the parabola, which says that the tangent at P bisects ∠ F P P ′ (along with the definitional property that F P = P P ′ ). – Blue Jul 17, 2024 at 8:34 1 WebAfter the introduction of Cartesian coordinates, the focus-directrix property can be utilised to write the equations provided by the points of the conic section.
