{ . } denotes the fractional part function and [.] denotes the greatest integer function. Now, match the following lists:

If [.] denotes the greatest integer function, then match the following lists:

If F(x)=(sinpi[x])/({x}) then F(x) is (where {.} denotes fractional part function and [.] denotes greatest integer function and sgn(x) is a signum function)

If F(x)=(sinpi[x])/({x}) then F(x) is (where {.} denotes fractional part function and [.] denotes greatest integer function and sgn(x) is a signum function)

In the following ,[x] denotes the greatest integer less than or equal to x. Now, match th following lists:

Which of the following function is not periodic, where [.] denotes greatest integer function
