Esta es una página de prueba, como dijo Einstein $E=mc^2$.

Remember to surround formulas with left-quotes or \$-signs:
`sum_(i=1)^n i=(n(n+1))/2` and $int_0^(pi/2) sinx\ dx=1$.

Note: this page uses relative links to ASCIIMathML.js and pmathml.xsl,
so these files should be in the same folder as this file.

Test $\frac{d}{dx}f(x)=\lim_{h\to 0}\frac{f(x+h)-f(x)}{h}$
