A) \[l,\]the set of integers
B) N, the set of natural numbers
C) W, the set of whole numbers
D) Q, the set of rational numbers
Correct Answer: B
Solution :
\[\because \] \[0<\{x\}<1\] \[0<\sin \,\{x\}<\sin \,1\] Also, \[\frac{1}{\sin \,\{x\}}>0\] Then, \[\left[ \frac{1}{\sin \,\{x\}} \right]=1,\,2,\,3,...\] \[\therefore \] \[{{R}_{f}}=N\]
