x2/3 + y2/2 = 1 (in standerd form)
eq of tangent at any point to ellipse is : y = mx +(-) (a2m2+b2)1/2
let point of intersection is (p,q) then it will satisfy the eq of tangent
q = mp +(-) (a2m2+b2)1/2 (a2 = 3 , b2=2)
(q - mp) = (3m2+2)1/2
squaring both sides & then we get a eq in terms of m ,
m2(p2-3) - 2mpq + q2-2 = 0 ....................1
this is quadratic in m , it is given that tangents substent 90o at center then product of
slopes of these tangents will be = -1 ..
from eq 1 , m1m2 = q2-2/p2-3 = -1
p2+q2 = 5
this is eq of circle & its eccntricity is 0 ...
