**texvc** (**TeX validator and converter**) is a program which renders mathematical formulae in LaTeX-syntax and outputs graphics that are embedded in wiki articles.

Click on *edit* to view the LaTeX-syntax in between the *math*-tag. If texvc is not installed in your Mediawiki-Installation the graphics output is not visible.

Here are some examples of LaTeX output produced in this manner:

- <math>\int_a^xf(\zeta\,z)\,dx</math>
- <math>\int_1^\infty \frac{1}{k^2}\,dk</math>
- <math>\sqrt{x^2+2x+1}=|x+1| - ((\frac{2x^2}{x})^2)^2</math>
- <math>\ E = \sum_{i=1}^N e^{- J_{ij} \sigma_i \sigma_j} </math>
- <math>\ \Phi = \frac{Q}{2\pi}\log(z-z_w) </math>

**Ok. So we had a problem. The math equations were not working yet. They seem to be fine now.**

jsMathTest shows how to use jsMath instead. In that case, the above equations become:

- $$\int_a^x f(\alpha\,)\,dx$$
- $$\int_1^\infty \frac{1}{k}\,dk$$
- $$\sqrt{x^2+2x+1}=|x+1| - ((\frac{2x^2}{x})^2)^2$$
- $$\ E = \sum_{i=1}^N e^{- J_{ij} \sigma_i \sigma_j}$$

And here is a comparison of how these two options look for the Cauchy singular integral:

- TeXvc:
<math>\Omega(z) = \frac{1}{2\pi i}\int_{\Gamma}{\frac{\lambda(\delta)}{z-\delta}d\delta}</math> - jsMath: $$\Omega(z) = \frac{1}{2\pi i}\int_{\Gamma}{\frac{\lambda(\delta)}{z-\delta}d\delta}$$
