A) 1
B) \[\pi /180\]
C) Does not exist
D) None of these
Correct Answer: B
Solution :
\[\underset{x\to 0}{\mathop{\lim }}\,\,\frac{\sin {{x}^{o}}}{x}=\underset{x\to 0}{\mathop{\lim }}\,\,\frac{\sin \frac{\pi x}{180}}{x}=\frac{\pi }{180}\] \[\left\{ \because \,x{}^\circ =\frac{\pi x}{180}\,radian \right\}\].
