Hello Everyone,
We have added all of MathJax's extensions to our script, so we have many new commands available. You can read about them here:
http://docs.mathjax.org/en/latest/tex.html#tex-and-latex-extensions
Here are some examples of our new extensions:
Bbox:
$$\bbox[5px,border:2px solid red]{\frac{x}{y}}$$
$$\color{white}\bbox[5px,blue]{\sum_{k=0}^n\left(k^3 \right)=\left(\sum_{k=0}^n\left(k \right) \right)^2}$$
Cancel:
The cancel commands (we previously had this extension, but we thought it would be good to show the variants):
$$\frac{\cancel{a}x}{\cancel{a}}=x$$
$$\frac{\bcancel{a}x}{\bcancel{a}}=x$$
$$\frac{\xcancel{a}x}{\xcancel{a}}=x$$
Chemical equations:
$$\ce{SO4^2- + Ba^2+ -> BaSO4 v}$$
Enclose:
$$\enclose{circle}[mathcolor="red"]{\color{black}{x}}$$
$$\enclose{circle,box}{x}$$
$$13\enclose{longdiv}{169}$$
$$\enclose{left}{\frac{x}{y}}$$
Extpfeil:
$$x\xtwoheadrightarrow y$$
$$x\xtwoheadleftarrow y$$
$$x\xmapsto y$$
$$x\xlongequal y$$
$$x\xtofrom y$$
You can even define your own arrow as follows:
$$\Newextarrow{\xrightharpoonup}{5,10}{0x21C0}$$
and then use it thereafter (in that post):
$$x\xrightharpoonup y$$
Text tip:
This allows you to define information the will pop up when the mouse cursor hovers over your expression.
$$\texttip{\int_a^b f(x)\,dx=F(b)-F(a)}{The Anti-Derivative form of The Fundamental Theorem of Calculus}$$
Unicodes:
$$\unicode[.55,0.05]{x22D6}$$
