ASCIIMathML Formulae
====================

http://www1.chapman.edu/~jipsen/mathml/asciimath.html[ASCIIMathML] is
a clever JavaScript written by Peter Jipsen that transforms
mathematical formulae written in plain text to standard mathematical
notation on an HTML page. See 'Appendix I' in the AsciiDoc User Guide
for more details.

The AsciiDoc `xhtml11` backend supports ASCIIMathML -- it links the
ASCIIMathML script and escapes ASCIIMathML delimiters and special
characters to yield valid XHTML. To use ASCIIMathML:

1. Include the `-a asciimath` command-line option when you run
   `asciidoc(1)`.
2. Enclose ASCIIMathML formulas inside double-dollar passthroughs.

Here's the link:asciimath.txt[AsciiDoc source] that generated this
page.

.NOTE
- If the formulas don't appear to be correct you probably need to
  install the correct math fonts (see the
  http://www1.chapman.edu/~jipsen/mathml/asciimath.html[ASCIIMathML]
  website for details).
- See the link:latexmath.html[LaTeXMathML page] if you prefer to use
  LaTeX math formulas.

A list of formulas with a mixture of formatting:

- $$`[[a,b],[c,d]]((n),(k))`$$
- $$`x/x={(1,if x!=0),(text{undefined},if x=0):}`$$
- $$`d/dxf(x)=lim_(h->0)(f(x+h)-f(x))/h`$$
- Red [red]$$`sum_(i=1)\^n i=(n(n+1))/2`$$ and [blue]*bold
  $$`int_0\^(pi/2) sinx\ dx=1`$$*
- [,,1.5]## 1.5 times normal size $$`(a,b]={x in RR : a < x <= b}`$$##
- A [,,2]##big## [blue]##blue## formula [blue,,2]$$`x^2+y_1+z_12^34`$$.
- [green,yellow,4]$$`x^2+y_1+z_12^34`$$

*********************************************************************
The first three terms factor to give
[red]$$$(x+b/(2a))^2=(b^2)/(4a^2)-c/a$$$.  Now we take square roots on
both sides and get [red]$$$x+b/(2a)=+-sqrt((b^2)/(4a^2)-c/a)$$$.
Finally we move the [red]$$$b/(2a)$$$ to the right and simplify to get
the two solutions: [red]*$$`x_(1,2)=(-b+-sqrt(b^2-4ac))/(2a)`$$*.
