If a chord joining two points A,B whose eccentric angles are α,β cut – InterviewSolution

1.	If a chord joining two points A,B whose eccentric angles are α,β cuts the major axis of the ellipse x225+y216=1 at a distance 1 from the centre, then ∣∣3tanα2tanβ2∣∣=
Answer» If a chord joining two points $A, B$ whose eccentric angles are $α, β$ cuts the major axis of the ellipse $\frac{x^{2}}{25} + \frac{y^{2}}{16} = 1$ at a distance $1$ from the centre, then $∣ ∣ 3 tan \frac{α}{2} tan \frac{β}{2} ∣ ∣ =$
