A reference: Mathjax, the client that I'm using to enable LaTeX on these forums, does not support all LaTeX symbols. There's a possibility that I'll be extending its support, but it's not my first priority (the way that homework is) so it may take awhile. In the meantime, look here if you are interested in a list of all symbols supported by Mathjax:
www.onemathematicalcat.org/MathJaxDocumentation/TeXSyntax.htm#SIt has a handy search function, so it may be handy as a general lookup table of LaTeX commands too!
Additional commands are being implemented and are listed below:
\(\newcommand{\dd}{\; \mathrm{d}}
\newcommand{\khat}{\boldsymbol{\;\hat{k}}}
\newcommand{\jhat}{\boldsymbol{\;\hat{\jmath}}}
\newcommand{\ihat}{\boldsymbol{\;\hat{\imath}}}
\newcommand{\SStar}[1]{\stackrel{\sstar}{#1}}
\newcommand{\dd}{\; \mathrm{d}}
\newcommand{\sstar}{\;\star\star}
\newcommand{\Star}[1]{\stackrel{\star}{#1}}
