Math Formula Editor

Mathematical Formula Editor (TeX in HTML)

At the left $\Left$ write TeX between $ symbols:

$\sqrt{\frac{1.68\times10^9}{4.2\times10^{-4}}}=\sqrt{\frac{168\times10^7}{42\times10^{-5}}}=\sqrt{\frac{2\times2\times2\times3\times7}{2\times3\times7}\cdot\frac{10^7}{10^{-5}}}$

$=\sqrt{\frac{2\times2\times\strike{2\times3\times7}}{\strike{2\times3\times7}}\times10^{7-(-5)}}=\sqrt{4\times10^{12}}=2\times10^6$

Outside $ signs it's just HTML; double $$ for a dollar-sign. You can also put a [number] before the $ to specify a size. More examples:

$f(x)=\smashmargin2{\int\nolimits_{x}}^{\infty}\quad\frac{1}{z^2}{\quad}dz$ , ${\angle}ABC=60^\circ$ , and $\bar{xy}=2.3\hspace{5}\text{cm}$

The TeX variant used is mimeTeX, documented here. The translated HTML code will contain images hosted by the speedy Google Chart Server. Once things look the way you want, just copy and paste the HTML code $\down$ below $\down$ right into your webpage.
