The minimum distance between the curves y = tan x, 
and 
is
A
- 1
B
- 1
C
+ l
D
2
Text Solution
Verified by ExpertsThe correct answer is:
B
- 1
The minimum distance between two curves lies along their common normal.
Let, P (h, tanh) lies on y = tan x
Then, the equation of normal at P
is y-tanh = - 
(x-h)
this passes through the centre of the circle, hence,
Minimum distance = distance between 
and
