If `f(x)=[tan^(2)x]` then (where `[ast]` denotes the greatest integer function)

If f(x) = [x^(-2) [x^(2)]] , (where [*] denotes the greatest integer function) x ne 0 , then incorrect statement

If f(x) = [x^(-2) [x^(2)]] , (where [*] denotes the greatest integer function) x ne 0 , then incorrect statement

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

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

The function f(x)=[x]^(2)+[-x^(2)] , where [.] denotes the greatest integer function, is

The function f(x)=[x^(2)]+[-x]^(2) , where [.] denotes the greatest integer function, is

f(x)=[tan^(-1)x] where [.] denotes the greatest integer function, is discontinous at

f(x)=[tan^(-1)x] where [.] denotes the greatest integer function, is discontinous at

The function f(x) = [x]^2-[x^2] (where [.] denotes the greatest integer function ) is discontinuous at

For a function f(x)=(2(x^(2)+1))/([x]) (where [.] denotes the greatest integer function), if 1lexlt4 . Then
