the square root of the difference, write $\sqrt{A-B}$. Alternately, go
to Math mode in LyX, rather than TeX mode, and enter \sqrt . If you
then hit the space bar, you see a little blue square root sign, with a
blue box inside, and the cursor in the box. Then enter A-B. Easier,
and you see what you will get.
Maybe it's worth adding that "TeX Code" (aka ERT, Evil Red Text), is
intended for various sorts of constructionw that LyX does not natively
support, or doesn't support very naturally. As David said, most math can
be done in LyX's math mode.

Insert Tex Code
Hello forum,
I am trying to insert TeX code directly from the LyX interface Insert->Tex
Code . Then I see a box in the editor. Inside the box I entered the
following:
\sqrt A-B
When I go for preview I get the following error:
//
Errors:
Missing $ inserted
Description:
on \emph{L, }and any vector \sqrt A
-B
I've inserted a begin-math/end-math symbol since I think
you left one out. Proceed, with fingers crossed.
//
Any hint on what is missing in the process ?
Thanks

However, you can insert custom headers/footers by following the instructions in the User's guide, section 6.11 (llok it up, it's very short). As for changing fonts: if you mean changing to a different fonts within the same typeface (i.e from roman to bold or bold italic, or small caps), you can do it by selecting the text in question, and then going to Edit>>Text Style>>Customized. If by "changing fonts" you mean "changing typefaces" (e.g. going from Times to Palatino), well, that it is typically not done at the text level. You can select the typeface at the document level (go Document>>Settings>>Fonts). Changing the typeface for different elements in your documents (i.e. headers, TOC, etc) may be done in different ways depending on which Document class you are using. The Koma-script classes, for instance, have their own commands that allow you to change the fonts in various areas of the documents (Headings, Footnotes, etcetera). I forget the details, but their documentation it's excellent: Look up the file scrguien.pdf or the more comprehensive German version: scrguide.pdf (both should be part of your TeX installation). The memoir class offers similar font-changing commands (see memman.pdf) If you really need to change typefaces at the micro level, you may want to look into the fontspec package (which, however, requires the XeTeX or LuaTeX backends, not the standard pdfLaTeX). Or you may want to use the Latex commands detailed in this page: http://latex.computersci.org/Reference/Typefaces Notice that, as that page says, these commands are typically NOT used in a document---they are meant for classes definitions. The same is true for the fontspec commands.Or take a look at the LaTex Companion to Latex---the font chapter (I believe it's chapter 6 or chapter 7). If you are trying to use Lyx as a standard word processor, changing styles and typefaces on a ad hoc basis, you are on the wrong track and you'll be wasting a lot of time. LyX is meant to be used in conjunction with a document class. It is the class that takes the design decisions (with some fine tuning, if necessary). If you want to constantly override the decisions taken by the document class, you may be using the wrong approach. I would switch to either a standard word-processor, plain TeX, or a page layout application (e.g. InDesign, Scribus), depending on your needs and background skills.

lyx 2.0.1: insert tex-code does not work
Dear Lyx-Users
If I insert in the red box direct the tex-code, see
http://www.quora.com/How-can-I-edit-LaTeX-source-code-in-LyX
f.e.:
\documentclass[english]{article}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}
\usepackage{babel}
\begin{document}
adfaf
\end{document}
following error report appears:
\documentclass
[english]{article}
Your command was ignored.
Type Ito replace it with another command,
orto continue without it.
What is wrong with that?

Joerg
Insert TEX code with right to left language text (persian,arabic, ...)
Hello!
When inserted Tex code with Persian words (RTL language)
my words in Persian is shown in lyx editor in LTR
for example like this
\rl{ی ل ت}
but this is correct:
\rl{تلی}
How can i insert both RTL and LTR texts in TeX mode?
