Question

Locate the discontinuities of the function.
y = ln((tan(x))^2)

Answer 1

\[\ln ((\tan (x))^2)\]

Answer 2

this is what I got in Maple...
I hope it will help

Answer 3

Function has discontinuities, when:
\[\tan{x}=0\] or\[\tan{x}\rightarrow\pm\infty\]
\[\Rightarrow\quad x=k\frac{\pi}{2}\enspace,\enspace k\in\mathbb{Z}\]
