Typos.

    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_M_Tag}). 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.
