Question

The length of the chord of the ellipse x2/25 + y2/16 = 1 where mid-point is (1/2,2/3)?

Answer 1

The length of the chord of the ellipse x2/25 + y2/16 = 1 where mid-point is (1/2,2/5)

Let "T" be the equation of the chord.

Let "*" denote the equation of the ellipse.

Then the chord having its middle point as (x1, y1) is given by
