Energypedia also offers the possibility to include formulas in an article. To insert a formula: 
1. Open the article in edit mode and switch to "wiki text editor"
Error creating thumbnail: convert: unable to open image `/var/www/ISWiki/prod/current/energypedia/images/1/1a/Show_Wiki_Text_Editor.JPG': No such file or directory @ error/blob.c/OpenBlob/2641.
 convert: no images defined `/tmp/transform_1aaf4ec-1.jpg' @ error/convert.c/ConvertImageCommand/3044.
 
 
2. Click on "Mathematical formula (LaTeX)"
The Wikitext code for an example formula looks like this: <math>
 \operatorname{erfc}(x) =
 \frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt =
 \frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}}
 </math> 
Which results in a formula like this:
Failed to parse (PNG conversion failed; check for correct installation of latex and dvipng (or dvips + gs + convert)): \operatorname{erfc}(x) = \frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt = \frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}}
What you see is:
- The overall formula needs to be enclosed by <math> and </math> tags.
 - The formula itself is written in LaTeX code
