\documentclass[a4paper]{article} \usepackage[english]{babel} \usepackage[utf8x]{inputenc} \usepackage{amsmath} \usepackage{graphicx} \usepackage[colorinlistoftodos]{todonotes} \title{Your Paper} \author{You} \begin{document} \maketitle \begin{abstract} Your abstract. \end{abstract} \section{Introduction} == edited through authorea. ==  Your introduction goes here! Some examples of commonly used commands and features are listed below, to help you get started. \section{Some \LaTeX{} Examples} \label{sec:examples} \subsection{Sections} Use section and subsection commands to organize your document. \LaTeX{} handles all the formatting and numbering automatically. Use ref and label commands for cross-references. \subsection{Comments} Comments can be added to the margins of the document using the \todo{Here's a comment in the margin!} todo command, as shown in the example on the right. You can also add inline comments too: \todo[inline, color=green!40]{This is an inline comment.} \subsection{Tables and Figures} Use the table and tabular commands for basic tables --- see Table~\ref{tab:widgets}, for example. You can upload a figure (JPEG, PNG or PDF) using the files menu. To include it in your document, use the includegraphics command as in the code for Figure~\ref{fig:frog} below. \begin{table} \centering \begin{tabular}{l|r} Item & Quantity \\\hline Widgets & 42 \\ Gadgets & 13 \end{tabular} \caption{\label{tab:widgets}An example table.} \end{table} \subsection{Mathematics} \LaTeX{} is great at typesetting mathematics. Let $X_2, X_3, X_5, \ldots, X_n$ be a sequence of independent and identically distributed random variables with $\text{E}[X_i] = \mu$ and $\text{Var}[X_i] = \sigma^2 < \infty$, and let $$S_n = \frac{X_1 + X_2 + \cdots + X_n}{n} = \frac{1}{n}\sum_{i}^{n} X_i$$ denote their mean. Then as $n$ approaches infinity, the random variables $\sqrt{n}(S_n - \mu)$ converge in distribution to a normal $\mathcal{N}(0, \sigma^2)$. \subsection{Lists} You can make lists with automatic numbering \dots \begin{enumerate} \item Like this, \item and like this. \end{enumerate} \dots or bullet points \dots \begin{itemize} \item Like this, \item and like this. \end{itemize} We hope you find write\LaTeX\ useful, and please let us know if you have any feedback using the help menu above. \end{document}
