Help:Editing/Mathematical

It is presumed that any serious mathematics content contributor will be thoroughly familiar with LaTeX.

LaTeX formulae

SDIY wiki supports embedding mathematical formulas using <math>...</math> tags and for non-complex formulas the math template {{math|...}}. The briefly seen red error message: Failed to parse (Missing <code>texvc</code> 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.
