Try to do $\alpha^T \beta$ using insert sysmbol.
Try to do $\sum$ part with word

Now go to Latex

Try $\alpha , \beta , \omega , \gamma $

Try
$x^Ty$  and
$x_i$

Try  $\sum _{i=1}^{n}$ 

Try $\int_a^b$

New paragraph is just obtained by putting a blank line so that now we can do a new paragraph}

$$\frac{x}{y}$$


\section{To label equations:}

\begin{equation}
\label{eq:temp}
\frac{ d^2 y}{d x^2} = mass \times acceleration
\end{equation}

A fundamental law in physics is (\ref{eq:temp}).

\section{Tabbing}
To do tabbing:
\begin{tabbing}
1. This is \=line 1\=\\
2. This is line 2\\
\> this line indented line a\\
\> \> this is double indented line b\\
\end{tabbing}
