Question
If the normal at the point 
to the ellipse 
intersects it again at the point 
, then 
is
- 2/3
- -2/3
- 3/4
- none of these.
Hint:
In this question we will write the parametric equation of points on the ellipse using the given angle, then we will find their slope also we will find the equation of the normal in the parametric form. Then we will equate the two slopes and simplify the equation using trigonometric identities and find the required trigonometric ratio.
The correct answer is: -2/3
