Question
Find the equation of pair of tangents drawn from the point (1, 2) and (2, 1) to the ellipse .

None of these



easy
Solution
As the point (1, 2) lies outside the ellipse, so equation of the pair of tangents drawn from it is
.
As the point (2, 1) lies inside the ellipse, so no tangent can be drawn from it.
