If `f(x) =2 [x]+ cos x`, then `f: R ->R` is: (where [ ] denotes greatest integer function)

If f(x)=2[x]+cos x, then f:R rarr R is: (where [] denotes greatest integer function)

If f: R to R is function defined by f(x) = [x-1] cos ( (2x -1)/(2)) pi , where [.] denotes the greatest integer function , then f is :

If f(x) = [x] - [x/4], x in R where [x] denotes the greatest integer function, then

If f(x)=[2x], where [.] denotes the greatest integer function,then

The number of integers in the range of function f(x)=[sin x]+[cos x]+[sin x+cos x] is (where [.]= denotes greatest integer function)

If f(x)= sin^(-1)x and g(x)=[sin(cosx)]+[cos(sinx)], then range of f(g(x)) is (where [*] denotes greatest integer function)

If f:R to R is function defined by f(x) = [x]^3 cos ((2x-1)/2)pi , where [x] denotes the greatest integer function, then f is :

f(x)=1+[cos x]x, in 0<=x<=(x)/(2) (where [.] denotes greatest integer function)

f(x)=1+[cos x]x in 0<=x<=(pi)/(2) (where [.] denotes greatest integer function)
