Road Sign Math

For quite some time we have searched for better ways to display the formulas for our mathematically significant roadsigns. The obvious place to look was for MathML, however, browser support for MathML is almost nil.

A visitor to Road Sign Math pointed out a great tool called jsMath written by Davide P. Cervone. This JavaScript library has proven to be a great way to display math functions on the web. It allows you to embed TeX commands into your HTML and then turn that into well formatted functions. As a result, you will not have to suffer through things like

( 4 + 5) / 3 = 3

and instead the much better looking

or even more substantially we can show a real square root, so the former notation of

SqRt(9) = 3

changes to the much more appropriate

Hats off to Davide for such a great tool!

One of the only downsides of this is that the math will show up as “raw” TeX commands in the RSS feed. You will have to click onto the link and go to the website to see the math solution formatted properly.
