any of you gurus have any experience with quotients, roots and the like on html pages produced by a standard lamp install? i'd like php to generate the formula randomly, which is easy, except i cannot display it properly... my only success was with exponents using <sup> . my next idea is to try to generate roots graphically with php's gd, but i thought there may be a simple way to do it. surely, someone has tried this before me...
thanks for your help

You should check MathML.

thanks a lot for the replies!

would you be able to be more specific about w3schools.com? i ran a few google searches with "site:w3schools.com" and couldnt find it there- would you be able to point me to the exact link there? thanks

as for MathML, this seems to be exactly what i need, except that it is not supported by a default installation of any browser i know (firefox, safari, etc)... guess is have to generate images of the formulae with some graphics.

correction: it actually does seem to work with firefox, but not with my safari, my cell phone, etc...
but at least firefox is something to start with

Yeah, only recent Gecko versions can render MathML. If you want a cross-browser solution, the best option is to generate PNG images from server-side. Here's a tutorial I found about using PHP to display LaTeX equations.
