Overview

Begin And End

Code

To insert computer code or even an block of data it often looks better if you place it within a 'code' block which will then highlight keywords and format numbers etc. This code block will be used in all our examples on this page:

\begin{code}
int fn(int a, double b)
{
\ do something here
return a+b;
}
\end{code}
gives

int fn(int a, double b)
{
  \\ do something here
  return a+b;
}

Tables

To insert a table use:

\begin{tabular}
a & b & c \\
d & e & f \\
g & h & i \\
\end{tabular}

To give:

a b cd e fg h i

The key points to remember are:

• to separate cells use '&' with a space either side.
• to start a new row use '\\' at the end of the line with a space before.

Quote

To insert a quote into your text, use:

\begin{quote}
The quick brown fox jumps over the lazy dog
\end{quote}

The quick brown fox jumps over the lazy dog

Yellow

To make an important note or warning stand out, use

\begin{yellow}
The quick brown fox jumps over the lazy dog
\end{yellow}

The quick brown fox jumps over the lazy dog

Center

To center a piece of text

\begin{center}
The quick brown fox jumps over the lazy dog
\end{center}

The quick brown fox jumps over the lazy dog

Right

To place some text on the right size of the screen within a separate area

\begin{right}
The quick brown fox jumps over the lazy dog
\end{right}
This is the normal text

Equation

There are several ways to write an equation, usually we recommend you use '\[' and '\]', see below. However, you can also use 'equation' within a begin-end block

\begin{equation}
e=mc^2
\end{equation}

(1)

Equations

\[e=mc^2\]

(2)

\(v^2=u^2+2as\)

For equations that you want to appear on the same line as the text, we use dollar symbols:

The first greek letter, $\alpha$ over the second, $\beta$, is $\frac{\alpha}{\beta}$.

The first greek letter, $\alpha$ over the second, $\beta$, is $\displaystyle \frac{\alpha}{\beta}$.

Equation Numbering

To the right of all block equation, an equation number is automatically added. This starts at '1' for the first block equation on the page and continues sequently. Often within the text you would like to refer to the equation. e.g. Equation (2) was derived by Einstein.

In long documents it is frequently very difficult to keep track of the equations numbers, and if you add an addition equation then equations assigned to equations after than added will all increase. To resolve this we allow you to assign you own internal number to any equation you write and refer to this within your text. We therefore introduce the hash, as in # to identify equations and refer to them later. e.g.

\[f=ma\]#42
\[v=u+2 a s\]#43
Newton wrote equation #42 all by himself. Equation (#43) helps you find 
the final velocity of an object given its starting speed, acceleration and time of acceleration.

(4)

Newton wrote equation 3 all by himself. Equation (4) helps you find the final velocity of an object given its starting speed, acceleration and time of acceleration.
