Let B be the centre of the circle x2 + y2 $$-$$ 2x + 4y + 1 = 0. Let the tangents at two points P and Q on the circle intersect at the point A(3, 1). Then 8.$$\left( {{{area\,\Delta APQ} \over {area\,\Delta BPQ}}} \right)$$ is equal to _____________. | 677.169 | 1 |
Problem 2 – Hint 5
Hint 3 defined A and B as the images of the points where the ellipse touches the tangents of the ellipse drawn from the point F. Continuing from where Hint 3 ended, the midpoint C of the segment AB is the centre of the circle (why?). | 677.169 | 1 |
