Question

29. Eccentricity of a conic is ratio of distance of a point on the conic from a fixed point to its distance from a fixed line. For an ellipse it lies between 0 and 1. Q. The ends of the major axis of an ellipse are (-2,4) and (2,1). If the point (1,3) lies on the ellipse, then find its eccentricity and latus rectum. Q. The line 3x - 4y =12 is a tangent to the ellipse with foci (-2,3) and (-1,0). Find eccentricity of the ellipse.
