## LaTeX – Detexify ~ a shout out

[latexpage]
Here’s how to easily find symbols in LaTeX.

Okay the most handiness (is that really a word?) little web app that I’ve come across since starting work in $\LaTeX$ is this little tool found here.
http://detexify.kirelabs.org/classify.html

$\text{detextify}^2$ has seriously saved me hours of my life.

This beautiful app lets you draw any symbol into a box, then it will return the corresponding $\LaTeX$ command. So freakin’ handy! And it works. That obscure symbol you saw in some paper $\zeta$, and you can’t think of the Greek name of the top of your head? Simple! Just draw it in and bam, $\text{detextify}^2$ throws the command back (\zeta in case you are wondering).

I use this all the time when I’m writing anything sort of equations in LaTeX. A definite must know about.

Hope this saves you countless sleepless nights.

## LaTeX – bold vectors and arrow vectors

Lately I’m writing a lot of papers in $\LaTeX$ and every once and a while something comes up that drives me crazy trying to figure out.

Here’s how to easily switch between a bold vector $\boldsymbol{x}$ and an arrow vector $\vec{x}$.

 % Minimal latex example: % Shows how to switch between bold and arrow vectors.   % Specifies the type of document you have. \documentclass{article}   % Used for the boldsymbol. \usepackage{amsmath}   % Comment this out to represent vectors with an arrow on top. % Uncomment this to represent vectors as bold symbols. \renewcommand{\vec}[1]{\boldsymbol{#1}}   % Start of the document. \begin{document}   % Your content. My lovely vector: $\vec{x}$   % End of the document. \end{document}
