# Some LaTeX Examples

\label{sec:examples}

## 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.

Comments can be added to the margins of the document using the todo command, as shown in the example on the right. You can also add inline comments too:

## 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.

## 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 $$\mathcal{N}(0, \sigma^2)$$.

## Lists
