Hi,

I am just trying to learn how to use latex!

\sqrt{4}=2

\int {x}^{3 }dx

\int {x}^{3}dx

After looking at the preview this doesn't look correct. Can someone please help me out?

You need to wrap them in tex tags

Code:`$\displaystyle \int_{a}^{b}f(x) \, dx $`

Code:`$\displaystyle \sqrt{4}=2 $`

$\displaystyle \sqrt{4}=2 $

$\displaystyle \int_{a}^{b}f(x) \, dx$

Why is the integral giving me an error? I wrote \int_{a}^{b}f(x) \, dx with {math} at the beginning and {/math} at the end? I DID use [] instead of {} - May 26th 2011, 08:28 AMTheEmptySet

Tip: if you want to display actual LaTeX code, use the noparse tags around the whole thing. Then you can avoid awkward circumlocutions such as "but without the space".

$\displaystyle

M =

\left( {\begin{array}{cc}

x & y \\

z & w \\

\end{array} } \right)

$

$\displaystyle \begin{bmatrix}1 & 3\\ 2 & 4\end{bmatrix}

$

I'm bad at matrix latex :( - Sep 29th 2011, 09:05 AMPlatoRe: test, this is only a test of the latex system
Here is the cleaned up LateX.

**Remove any line feeds.**

[TEX]M =\left( {\begin{array}{cc} x & y \\ z & w \\ \end{array} } \right)[/TEX]

[tex]\begin{bmatrix}1 & 3\\ 2 & 4\end{bmatrix}[/tex]

$\displaystyle M =\left( {\begin{array}{cc} x & y \\ z & w \\ \end{array} } \right)$

$\displaystyle \begin{bmatrix}1 & 3\\ 2 & 4\end{bmatrix}$
