Question
Let P(6, 3) be a point on the hyperbola 
. If the normal at the point P intersects the x-axis at (9, 0), then the eccentricity of the hyperbola is
. If the normal at the point P intersects the x-axis at (9, 0), then the eccentricity of the hyperbola is Options
A.
B.
C.√2
D.√3
Solution
Equation of normal is (y - 3) = 
(x - 6) ⇒ 
= 1 ⇒ e = 
(x - 6) ⇒ = 1 ⇒ e = Create a free account to view solution
