LaTeX formulae
It is hoped that any serious mathematics content contributor will be thoroughly familiar with LaTeX. Otherwise to generate the text required to display equations, use the CodeCogs LaTeX Equation Generator.

SDIY wiki supports embedding mathematical formulas using  tags and for non-complex formulas the math template $...$. The red error message: Failed to parse (Missing executable. Please see math/README to configure.) etc. is due to server lag and does not indicate a real problem.

Example

It can easily be seen, by polynomial expansion, that the following equation is equivalent to the quadratic equation:
 * $$\left(x+\frac{b}{2a}\right)^2=\frac{b^2-4ac}{4a^2}$$

Taking the square root of both sides, and isolating $x$, gives:
 * $$x=\frac{-b\pm\sqrt{b^2-4ac\ }}{2a}$$

Charts
A way to do charts is still being worked on. In the mean time use images from your favoured applcation, also see Wikipedia:How to create charts for Wikipedia articles.
