Formula of latus rectum of ellipse
WebJan 29, 2024 · Here Latus rectum of ellipse and parabola are coincided, assuming p for parabola has same value as of ellipse, we can calculate it as follows: p = a ( 1 − e 2) where e is the eccentricity of ellipse, as you found is e = 3 5 and a = 5 ⇒ p = 5 [ 1 − ( 3 / 5) 2] = 16 5 Therefore the equation of parabola must be: y 2 = 2 × 16 5 × x = 32 5 x WebLet the equation of the ellipse be x2/a2 + y2/b2 = 1, where a2 > b2 For an ellipse, the eccentricity e = c/a ⇒ a = c/e where (±c, 0) is the focus ∴ a = 4/ (⅓ ) = 12. Now, c2 = (a2 – b2) ⇒ b2 = (a2 – c2) = 122 – 42 = 128 Hence, …
