If `y= (sqrt(1-sin4A)+1)/(sqrt(1+sin4A)-1)` then one if the values of `y` is (A) `-tanA` (B) `cotA` (C) `tan(pi/4+A)` (D) `-cot(pi/4+A)`

If x=(sqrt(1-sin4 theta)+1)/(sqrt(1+sin4 theta)-1) then one of the values of x is

If y=(sqrt(1-sin4x)+1)/(sqrt(1+sin 4x)-1) , then y can be

If y=tan^(-1)sqrt((1-sin x)/(1+sin x)), then the value of (dy)/(dx) at x=(pi)/(6) is.

If y=tan^(-1) sqrt((1-sin 4x)/(1+sin 4x)),"then " dy/dx=

If y=(x^(4)-x^(2)+1)/(x^(2)+sqrt(3)x+1) and (dy)/(dx)=ax+b then the value of a-b is (a)cot((pi)/(8))(b)cot((pi)/(12))(c)tan((5 pi)/(12))(d)tan((5 pi)/(8))

The value of tan^(-1) ( sqrt(2) sin "" ( 3 pi)/( 4)) is

If A-B=pi/4quad y=(1+tan A)(1-tan B) then value of (y)^(y+1)=
