The range of the function f defined by fx=1sinx (where [.] and {.}, respectively, denote the greatest integer and the fractional part functions) is
I, the set of integers
N, the set of natural numbers
W, the set of whole numbers
{1,2,3,4,...}
Since x∈0,1,sinx∈0,sin1 as f(x) is defined if sinx≠0 i.e.,
1sinx∈1sin1,∞ or 1sinx∈1,2,3,......
Note that, 1<π3 or sin1<sinπ3=0.866 or 1sin1>1.155.
