% This is math.etex, a demostration of the
% way SGML-Tools handle mathematical expressions.
% We rely on LaTeX as the most sophisticated
% formula processor available, decline on
% structured markup for formulas, and propose
% automatic conversion of Encapsulated LaTeX
% to GIF for other backends.
% ASCII art replacements will have to be created
% manually, as long as nobody writes a translator
% from LaTeX math expressions to ASCII.
% Comment: be careful with comments for
% inlined formulas, leave no blank lines
%
S(z) = -\cos( \frac{\pi}{2} z^2 ) \sum_{n=0}^\infty
\frac{ (-1)^n \pi^{2n+1} }{ 1 \cdot 3 \cdots (4n+3) } z^{4n+3}
% Beware of trailing blank lines for inlines.
