1   Writing Equations

Siafoo supports LaTeX based mathematical expression inside reST based content. There are two ways to display equations: inline with the text or in a separate block.

If you are unfamiliar with LaTeX we recommend reading through Andrew Robert's, Getting to Grips with Latex for a general idea of what LaTeX is and how to effectively use it in your work. Because [currently] Siafoo supports LaTeX in math mode only, we suggest concentrating your efforts on the the Mathematics Part I and Part II sections.

When you write an equation Siafoo will enclose it in either $, for inline math, or \begin{equation|equation*|align|align*}, for math blocks.

1.2   In Blocks

To get an equation block outside of the text use the math directive .. math:::

# 's

1.. math::
2
3 \nabla \cdot E = \frac{1}{\epsilon_0} \rho

which will produce:

For multiple equations you can use the align option:

# 's

1.. math:: align
2
3     \nabla \cdot E &= \frac{1}{\epsilon_0} \rho\\
4     \nabla \cdot B &= 0\\
5     \nabla \times E &= -\frac{\partial B}{\partial t}\\
6     \nabla \times B &= \mu_0 J + \mu_0 \epsilon_0 \frac{\partial E}{\partial t}

The equations will be aligned at the & symbol

or use align* to remove the numbers from the equations like...

Note that in order to indent the equation block you must indent everything including the .. math:: directive itself. Indenting only the equations will have no effect.

You can play with equations at the Siafoo reST demo
