    test, this is only a test of the latex system

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

    Code:
     
    
    
    
    
    \sqrt{4}=2 
    \sqrt{4}=2 \sqrt{4}=2

    \sqrt{4}=2

    \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 {}

    You are using [tex] [/ math]

    tags with out the space instead of

    [tex] [/ tex] tags

    Due to technical difficulties you must use the 2nd set of tags.

    [tex] \int_{a}^{b} f(x) \, dx [/ tex] again remove the space

    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".

    That is [noparse] [/noparse] tags.

    (and I am still surprised that that works correctly! )

    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]

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

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