How to write maths that looks like maths in a post (using LaTeX)

The YourMathsTutor Community Forum uses $\LaTeX$ commands as a way of including math notation in your posts. For example, if I have a question concerning integrating an equation then on some forums I would be forced to post something like this: -

the integral between -1 and 2 of the equation y = x³ - x² - 2x

...which can begin to get very hard to understand Huh

But on The Maths Forum you can use $\LaTeX$ to specify this equation. The $\LaTeX$ command for that equation looks like this:-

\int^2_{-1}(x^3 - x^2 - 2x)\,dx

Enclose this LaTeX code in [tex]...[/tex] tags before you post it and it will look like this: -

$\int^2_{-1}(x^3 - x^2 - 2x)\,dx$

...which is much easier to understand

There are three ways of writing maths code...

Write out the $\LaTeX$ command in full - including writing the [tex]...[/tex] tags yourself. Not for the faint-hearted .
Click on the LaTeX button. This inserts the [tex]...[/tex] tags automatically but you still have to write the $\LaTeX$ command yourself .

Use the DragMath editor. DragMath is an open-source drag and drop equation editor written in Java. Once you have created your expression it is automatically converted into a $\LaTeX$ command and inserted into your post. Click on the DragMath button to open the DragMath editor. The first time you open the editor you may see a security warning. If you do just click on accept/ok/run (whichever applies). DragMath is the easy way to include maths in your posts .
