Question

If  is a tangent to the ellipse , then find out the eccentric angle of the point of tangency.

Solution

Correct option is

450

The tangent can be written as              … (1)

The equation of tangent at point ‘θ’ is given as

                                                   … (2)

From (1) and (2), eccentricity angle θ = 450.
