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]*$$`x_(1,2)=(-b+-sqrt(b^2-4ac))/(2a)`$$*. *********************************************************************
