# How to write an aligned equation with itemize centred bullets in latex?

I need to write an inline equation with itemize in latex. I did the following:

\documentclass{article}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{dsfont}
\begin{document}
The following two bullets:
\begin{itemize}
\item \begin{aligned} \sum_{i=1}^{n}f_i(t)\cdot\hat{g}_{i}(t)&=\sum_{i=1}^{L}f_i(t)\cdot\left[g_{i}(t)/f_i(t)\right]\mathds{1}_{\{j\}}(i)\\&=g_{j}(t). \end{aligned}
\item $f_i(t)\leqslant g_i(t)$ for all $i$.
\end{itemize}
\end{document}


The first bullet is not centred as the following figure shows:

• Use \begin{aligned}[t]. By default, it is vertically centred. Jun 18, 2018 at 16:32

You just want \begin{aligned}[t]:

\documentclass{article}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{dsfont}

\begin{document}

The following two bullets:
\begin{itemize}
\item \begin{aligned}[t] \sum_{i=1}^{n}f_i(t)\cdot\hat{g}_{i}(t) &=\sum_{i=1}^{L}f_i(t)\cdot[g_{i}(t)/f_i(t)]\mathds{1}_{\{j\}}(i)\\ &=g_{j}(t). \end{aligned}
\item $f_i(t)\leqslant g_i(t)$ for all $i$.
\end{itemize}

\end{document}


• I never thought it was that easy! Thank you.
