A) 5
B) 6
C) 7
D) 1
Correct Answer: D
Solution :
As we are given \[f(x)=\sin x\], if \[x\ne n\pi \] i.e., \[x\ne 0,\,\pi ,\,\,2\pi ,....\]= 2 otherwise \[\therefore \,\,\,\underset{x\to {{0}^{+}}}{\mathop{\lim }}\,g\,\{f(x)\}=\,\underset{x\to {{0}^{+}}}{\mathop{\lim }}\,g\,\{\sin x\}=\,\underset{x\to {{0}^{+}}}{\mathop{\lim }}\,({{\sin }^{2}}x+1)\] = 1 Similarly, \[\,\underset{x\to {{0}^{-}}}{\mathop{\lim }}\,g\,\left\{ f(x) \right\}=1.\]You need to login to perform this action.
