    How can I ask questions that need symbols and equations to explain?

    Write your question neatly on paper. Take a picture of the page. Upload the picture to the forum.

    Note: This is the introduction part of the forum. Here we introduce ourselves. You know, your name, where you are from, the reason for joining the site, etc.

    I don't think so. When ever you write something using Latex, I can see only code.

    this, for example:
    "$ \sqrt {\frac {x^2}{3}} $" (without the spaces) renders as $\sqrt{\frac{x^2}{3}}$.

    On other sites [ tex ] [ \tex ] (without the spaces)
    on some [ math ] [/math ]
    and on yet others $ $
    are used for Latex.

    None of them seem to
    \(\sqrt{x^2}\)
    [math]\sqrt{x^2}[/math]
    $\sqrt{x^2}$​

    I've just seen this thread and added LaTex support for you guys. You can use the [ tex ] tags to use it :).

    Trial: \(\sum_{n= 0}^\infty \frac{x^n}{n!}= e^x\).

    \(\int_{-\infty}^\infty e^{-x^2}dx= \sqrt{2\pi}\).

    Does not seem to work.

    To get these I used
    \sum_{n= 0}^\infty \frac{x^n}{n!}= e^x and
    \int_{-\infty}^\infty e^{-x^2}dx= \sqrt{2\pi}[

    between [ tex ] and [ /tex ] without the spaces.

    There is a Latex tutorial at
    LaTeX math and equations - LaTeX-Tutorial.com

    Without spaces, huh? Let me try.

    [ tex ]x^2+y^2[ / tex ]
