Find focus of ellipse
WebTherefore, the eccentricity is. e = c a = 4 5. Now, the general (polar) form for an ellipse with a horizontal major axis, with the left focus as the pole, is. r ( θ) = e p 1 − e cos θ = 4 p / 5 1 − ( 4 cos θ) / 5. where p is the distance from the directrix of the ellipse to the pole. Now all that remains is to find p.
