Latex command\langle arg \rangle
Example\langle arg \rangle → 〈arg〉

You need to use the \langle arg \rangle command to write angle brackets in latex. But if the equation is large, I would not recommend using this command.

\documentclass{article}
\begin{document}
   \[ \langle x_1 , y_1 \rangle \]
   \[ \langle \frac{1}{a} , \frac{1}{b} \rangle \]
   \[ \langle \frac{1}{x^2} + \frac{1}{y^2} \rangle \]
\end{document}

Output :

Use angle brackets in latex.

If the equation is large, it would be best to use the \left\langle arg \left\rangle command. By this, the size of the bracket will be automatically adjusted according to the size of the equation.

\documentclass{article}
\begin{document}
   \[ \left\langle \frac{1}{a} , \frac{1}{b} \right\rangle \]
   \[ \left\langle \frac{1}{x^2} + \frac{1}{y^2} \right\rangle \]
\end{document}

Output :

Use angle brackets for big equation in latex.
