    LyX and MikTeX

    Hi !

    I've installed MikTex and then LyX.
    I've seen in the tutorial that one can directly type the latex code. That is "click on the Tex symbol" and then there is a red box where I can type the formula.
    However, in the tutorial, they're saying that if I type \gamma, it would produce the symbol and change color. But when I type it and then view it by DVI, I only get an error message, telling me to put the $ $.
    \bullet Indeed it works if I put $\gamma$. But why ? Do I have to put $ $ every time I type a formula ?

    Then, I tried to type
    Code:
    $\Gamma(s)=\int \limits_0^{\infty} e^{-t} t^{s-1} ~ dt$
    And viewed it by PDFviewer.
    \bullet The size is too small ! Especially the integral sign. How can I change it ?

    \bullet Is it possible to modify a pdf that is already existing ?

    \bullet And what is DVI ?

    \bullet Is there a specific font you would advice me ?

    \bullet They don't accept \mathbb{R} how can I do ?

    The questions may sound stupid, but I'm just a noob when it comes to get used to a new program


    Thanks in advance !

    Code:
    \documentclass[12pt]{article}
    \usepackage{amssymb} %this is for \mathbb code
    \begin{document}
    $\Gamma(s)=\displaystyle\int \limits_0^{\infty} e^{-t} t^{s-1} ~ dt$ for $s\in\mathbb{R}$.
    \end{document}
    works with me in WinEdt 5.5.

    LyX help

    the LateX button is for inserting raw code, in LateX you need to use the dollar signs to designate a formula.

    LyX has a special keyboard shortcut for math formulas, just type command(control)-shift-M and that will insert a floating formula where you can intuitively enter formulas.

    more math options can be found if you go to the 'insert' menu and select the 'math' submenu.

    hope that helped!
