To separate paragraphs, enter a double NEW LINE by pressing the ENTER key twice.

To enter nice looking formulae, enter them using the triple curly braces, like this: 
{{{x[1,2] = (-b +- sqrt( b^2-4ac ))/(2a) }}}

{{{ 
    sqrt( int( 1/(1+x^2), dx, -infinity, infinity ) ) 
}}}

To create graphs, use the same notation:

{{{graph( 600, 400, -10, 10, -20, 20, x^2-4x-3, x-2, 3-x ) }}}

That's a graph 600x400 pixels, x changes from -10 to +10, y changes from -20 to 20.
