Tangents are drawn from any point on the ellipse `x^2/9+y^2/4=1` to the circle `x^2+y^2=1` and respective chord of contact always touches a conic 'C', then -

Explanation

`x^2/9+y^2/4=1`
circle=`x^2+y^2=1`
`implies` cord of contact with respect to`(3,0)`

`3*x=1`
`x=1/3`
similarly for`(0,2)`

`y=1/2`
`b=1/2,a=1/3`
