    The points of discontinuity of tan x are

    A) \[n\pi ,\,\,n\in I\]

    B) \[2n\pi ,\,\,n\in I\]

    C) \[(2n+1)\frac{\pi }{2},\,\,n\in I\]

    D)  None of the above

    Correct Answer: C

    Solution :

    Let\[f(x)=\tan x\] The point of discontinuity of\[f(x)\]are those points where tan x is infinite. \[ie\],    \[\tan x=\tan \infty \] \[\Rightarrow \]               \[x=(2n+1)\frac{\pi }{2},\,\,n\in I\]
