If the tangent at θ on the ellipse x2a2+y2b2=1 meets the auxiliary c – InterviewSolution

1.	If the tangent at θ on the ellipse x2a2+y2b2=1 meets the auxiliary circle at two points which subtend a right angle at the centre, then e2(2−cos2θ)=
Answer» If the tangent at $θ$ on the ellipse $\frac{x^{2}}{a^{2}} + \frac{y^{2}}{b^{2}} = 1$ meets the auxiliary circle at two points which subtend a right angle at the centre, then $e^{2} (2 - {cos}^{2} θ) =$
