The distance between the directrices of the hyperbola x = 8 sec θ θ , y = 8 tan θ θ is
A
16 
B
C
8 
D
4 
Text Solution
Verified by ExpertsThe correct answer is:
B
Equation of hyperbola is
X = 8 sec θ θ , y = 8 tan θ θ ⇒ ⇒ 
= sec θ θ , 
= tan θ θ
sec 2 θ θ - tan 2 θ θ = 1 ⇒ ⇒ 
= 1
Here, a = 8, b = 8
Now, e = 
.
