# ASCIIMathML Formulae

version 8.2.1, 06 April 2007

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 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 ASCIIMathML website for details).

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 `sum_(i=1)\^n i=(n(n+1))/2` and bold `int_0\^(pi/2) sinx\ dx=1`

- 1.5 times normal size `(a,b]={x in RR : a < x <= b}`

- A big blue formula `x^2+y_1+z_12^34`.

- `x^2+y_1+z_12^34`

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