HEAD
Formulas within an <m> tag must be within $...$ or $$...$$. Without, printing (PDF creation) would fail.
1: \label{Authoring_HTML_vs_Tex}
2: LON-CAPA renders resources in several formats, including on the web in
3: HTML and in LaTeX for renderings designed to be printed.
4:
5: When creating problems, it is possible to use LaTeX directly by using
6: the <m> tag\index{m tag}\index{tag, <m>} (see
7: \ref{Authoring_Output_Tags}). Anything between the <m> tag in a resource
8: will be interpreted as .tex.
9:
10: However, this should be used as a last resort for when you wish to do
11: something that is impossible to do in HTML. LON-CAPA will convert to
12: and from LaTeX and HTML whenever necessary, and it is much easier (and
13: therefore more likely to work) to convert HTML to LaTeX then to go the
14: other direction, because HTML is so much simpler than LaTeX.
15:
16: Thus, given the choice of
17:
18: \texttt{H<sub>2</sub>O}
19:
20: or
21:
22: \texttt{$<$m$>$\$ H\textbackslash{}subscript\{2\}O \$$<$/m$>$}
23:
24: it is better to use the HMTL version.
25:
26: A necessarily-incomplete list of capabilities: LON-CAPA can convert
27: HTML tables in LaTeX tables, images into LaTeX images, LaTeX symbols
28: into HTML, and LaTeX math into HTML (though it does not usually look
29: as good as LaTeX).
30:
31: If you really wish to have the web rendering and the LaTeX rendering
32: do something different, perhaps because the automatically generated
33: LaTeX->HTML conversion did not do what you wanted, you can surround
34: your LaTeX with <tex> </tex>\index{tex tag}\index{tag, <tex>} tags,
35: and your HTML version with <web> </web>\index{web tag}\index{tag,
36: <web>} tags. The stuff placed between the <tex> tags will only show on
37: the LaTeX rendering of the resource, and the stuff placed between the
38: <web> tags will only show on the HTML web rendering of the resource.
