Let’s check out your problem:

Let $g(x)=\frac{1}{\tan ^{2}(x)}$.$\newline$Select the correct description of the one-sided limits of $g$ at $x=0$.$\newline$Choose $1$ answer:$\newline$(A)$\newline$$$\begin{array}{l} \lim _{x \rightarrow 0^{+}} g(x)=+\infty \text { and } \\ \lim _{x \rightarrow 0^{-}} g(x)=+\infty \end{array}$$$\newline$(B)$\newline$$$\begin{array}{l} \lim _{x \rightarrow 0^{+}} g(x)=+\infty \text { and } \\ \lim _{x \rightarrow 0^{-}} g(x)=-\infty \end{array}$$$\newline$(C)$\newline$$$\begin{array}{l} \lim _{x \rightarrow 0^{+}} g(x)=-\infty \text { and } \\ \lim _{x \rightarrow 0^{-}} g(x)=+\infty \end{array}$$$\newline$(D)$\newline$$$\begin{array}{l} \lim _{x \rightarrow 0^{+}} g(x)=-\infty \text { and } \\ \lim _{x \rightarrow 0^{-}} g(x)=-\infty \end{array}$$
