Question
A tangent to the ellipse
+
= 1 is cut by the tangent at the extremities of the major axis at T and T' and the circle on TT' as diameter passes through the point Q, then Q may be -
- (–
, 0)
- (2, 3)
- (0, 0)
- (3, 2)
The correct answer is: (–
, 0)


equation of tangent

The distance of the point '
' on the ellipse
from a focus is –
an ellipse has 2 focii at (ae,0 ) and (-ae,0) when the center is (0,0) and the ellipse has the x axis as its major axis. an ellipse is defined as the locus of a point whose sum of the distances from 2 fixed points (focii) is constant.
