We have to use an angle bracket for the inner product. You can use the \langle arg1,arg2 \rangle command for this but if the equation is borough size then I will not recommend this command. In the excerpt below, you can see that the size of the angle bracket in the fraction is not adjusting properly.

\begin{document}
$$ \langle u , \; v \rangle $$
$$ \langle \frac{1}{n} u , \; \frac{2}{n} v \rangle $$
\end{document}Output :
You need to use the \left\langle arg1,arg2 \right\rangle command to automatically adjust the angle bracket according to the size of the equation.

\begin{document}
$$ \left \langle \frac{1}{n} u , \; \frac{2}{n} v \right \rangle $$
$$ \left \langle \frac{1}{b_i} , \; \frac{2}{b_j} \right \rangle $$
\end{document}Output :
