It does seem strange

Here my LO running the code below: http://elearning.net.marjon.ac.uk/rlo/play.php?template_id=201

Can anyone else get proper symbols appearing in an LO using John's code:

<tex src="ax^2 + bx + c"></tex>
<br><br>are given by the formula
<br><tex src="\frac{-b \pm \sqrt{b^2 - 4ac}}{2a} "></tex>
<br><br><br>where
<br><tex src="a \neq 0"></tex>

Should display like:

[cid:image002.jpg at 01CBB980.75038AF0]

Not like this:

Bit lost then, because those are images returned from a server somewhere. Not sure why the requests from your machine / network for the same thing to the same place return different results...

Post the link to your object so we can run it?

Hi John

Thanks very much for providing the examples. However, mine still doesn't seem to want to render special characters.

First example:

[cid:image004.png at 01CBB980.75038AF0]

Returns this in Xerte:

[cid:image005.png at 01CBB980.75038AF0]

Any ideas?

This is the general equation where H is the Hamiltonian:

<br><br>For a single particle in three dimensions it can reduced to:

It's the $ in your example that seems to be causing the problems I think.  This works without them in:

<tex src="\sqrt{2}">

It's not my project. I did look at the raw xml, but it has a load of escaped characters in there which make it more difficult to copy / paste into a mail.  I have sent your message to the owner of the project.

No chance of seeing the text as it appears in that Xerte LO?!

That document doesn't really help at the moment as I can't replicate the examples in Xerte until im sure what to include and what not to!

For example, the document tells you to write:

\documentclass{article}
\begin{document}
The square root of two: $\sqrt{2}$. I can type math!
\end{document}

To output:

[cid:image011.png at 01CBB980.75038AF0]

But in Xerte

Renders:

[cid:image012.png at 01CBB980.75038AF0]

And

<tex src="The square root of two: $\sqrt{2}$. I can type math!"> renders:

[cid:image013.png at 01CBB980.75038AF0]

<tex src="$\sqrt{2}$"> just renders:

[cid:image014.png at 01CBB980.75038AF0]

Any ideas? I could probably work out what I'm missing from that example Nottingham LATEX LO!

I don't think there is anything 'funny' about the latex service we use. It is a third party service though, but we are working to implementing it ourselves,

Any chance of seeing the LATEX code to generate these equations:

http://www.nottingham.ac.uk/toolkits/play_595

My LO doesn't seem to want to do fancy graphic ones (e.g. special chars) - do you need to tell latex to load a set of chars? I can get it to render things like e=mc2 but not much else:

[cid:image015.png at 01CBB980.75038AF0]

Bl***y maths...

I've tried doing

<tex src="\usepackage{amsmath}"> to no avail.

Hi all

Is anyone using Math / Scientific symbols in Xerte? I've had a request for help from a Maths lecturer who needs to use symbols.

I've had a go using <sub> and <sup> which works in XOT with "allow subscripts" ticked, and also came across an earlier list post pointing out HTML chars which seem to work, but I also came across some reference to Latex.

Does latex work in XOT? Last I read it seemed some service you chaps used had crashed?

If there is an easier way than using HTML syntax then let me know. I guess another alternative would be to use some other software and save them as images.

Cheers, Adam
