Let `[.]` represent the greatest integer function and `f (x)=[tan^2 x]` then :

Let [] donots the greatest integer function and f (x)= [tan ^(2) x], then

If [x] represents the greatest integer function and f(x)=x-[x]-cos x" then "f^(1)(pi/2)=

If [x] represents the greatest integer function and f(x) = x - [x] - cos x, then f’((pi)/2) =

Let [*] representes the greatest integer function and [cos^(-1)(tan^(-1)x)]=2, then the maximum value of x is

Let [.] represents the greatest integer function and [cos^(-1)sin^(-1)tan^(-1)x]=1 then 'x' lies in the intervel.

Let [] represents the greatest integer function and [cos^(-1)sin^(-1)tan^(-1)x]=1 then 'x' lies in the intervel.
