Find the co-ordinate of the focus, equation of the directrix and length of the Latus Rectum of the parabola y2 = 8x. |
|
Answer» Equation of parabola y2 = 8x compare with the standard form y2 = 4ax ∴ 4a = 8 ∴ a = 2 ∴ focus = (a,0) = (2,0) Equation of directrix : x = -a. x = -2 or [x + 2 = 0] Latus rectum = 4a = 8. |
