पर्याय
\[x=2n\pi,\ n\in\mathbb{Z}\]
\[x=\dfrac{(2n+1)\pi}{2},\ n\in\mathbb{Z}\]
\[x=n\pi,\ n\in\mathbb{Z}\]
\[x=\dfrac{n\pi}{2},\ n\in\mathbb{Z}\]

उत्तर
The function \[\tan x\] is continuous wherever \[\cos x\neq 0\]. Since \[\cos x=0\] at \[x=\frac{(2n+1)\pi}{2}\], \[\tan x\] is not continuous at those values.
