\begin{abstract}
A tutorial of \LaTeX{} is presented. The format of a lab report in \LaTeX{} is discussed. Fronts and greek letters are shown to be within the capabilities of this software. Equations, figures, and tables are also created.
\end{abstract}
\section{Introduction}
This is where you write you lab report. You can do all kinds of fun things like {\bf Bold}, {\it italic}, \underline{underlined}, $a_{subscript}$, $a^{superscript}$, and an inline equation $f(x) = \sin(\omega t)$. I can also write equations separately in their own line.
\begin{equation} \label{eq:formula}
F = \int \int_0^\infty B_\nu d\nu d\Omega
\end{equation}
And write a multiple series of equations and align the '=' sign for each line.
\begin{align}
y &= e^x + \sqrt{x} \\
\frac{dy}{dx} &= e^x + \frac{1}{2}x^{-1/2}
\end{align}
I can also write greek letters is this: $\alpha\beta\Gamma\delta\sigma\zeta\xi$.Also, \LaTeX{} uses some special characters to denote things like equations so to display them normally you need to put a $\backslash$ before the character (e.g. \$, \%) although the backslash character itself is even more special. You'll probably also want to include figures in your lab report. Figures are tricky business in \LaTeX{}, but seee Fig. \ref{fig:example} as an exmaple of how to create and reference them. You can also reference equations: see Equation \ref{eq:formula}.

\caption {A hastliy constructed image to show how to include a figure in a lab report.} %always put captions before labels or else your figures won't get referenced properly
\label{fig:example}
\end{figure}
\section{Another Section}
You'll want to break up your report into sections to improve the clarity and strucutre of your paper.
\subsection{Subsections}
You can even use subsections if you want.
\subsubsection{Yes these exist}
Yup.
\section{Tables}
Table \ref{tab:example} shows how it can organize your results.
\begin{table}[!h]
\center
\begin{tabular}{|c|c|}
\hline
Left & Right \\
\hline
Bottom Left & $x^2$ \\
\hline
\end{tabular}
