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