41. ELLIPSE : A line intersects the ellipse x²/a² + y²/b²=1 at P and Q and the parabola y²=4d(x+a) at R and S. The line segment PQ subtends a right angle at the centre of the ellipse. Find the locus of the point of intersection of the tangents to the parabola at R and S. Click here to view details:
