# Handy Latex link

For anyone struggling to work out the Latex codes for different maths symbols, this link is very useful: http://detexify.kirelabs.org/classify.html

It lets you draw the symbol in the box and then offers you the most likely matches. Not seen it get it wrong yet. The only thing to watch for is which mode the recommended symbols are in, sometimes there’s a maths and text version, use the wrong one in a \begin{eqn*} section and it’ll be errors everywhere :). So far there’s been nothing it couldn’t work out for me, and it’s a hell of a lot easier than going through one of the huge Latex symbol charts on line.

As the Open University uses Latex to typeset their maths text books it would be nice if they could include a crib sheet of new symbols being introduced in each section (took me ages on MS221 to work out how to get the Unit Circle symbol)
