 A tangent drawn to the hyperbola x2a2y2b2=1 at Pπ6 forms a triangle of area 3a2 sq. units with the coordinate 

 axes. Then the square of its eccentricity is 

a
15
b
24
c
17
d
14

detailed solution

Correct option is C

Pasec⁡π6,btan⁡π6≡P2a3,b3Therefore, the equation of tangent at P is  x3a/2−y3b=1∴ Area of triangle =12×3a2×3b=3a2 or  ba=4 or  e2=1+b2a2=17
