# Toolbox

From aemwiki

**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>

And here is a real case example, the Cauchy singular integral:
