HI
I selected the filter Tex and algebric, but i can't see the image of the expression. If i access tohttp://omeusitio/moodle/filter/algebra/algebradebug.php
Option Show Db Entry I get:
DB cache_filters entry for sin(z)/(x^2+y^2) not found
Any help?
Thank you
P.S if i run c:\www.xxx\algebra\algebra2tex.pl x/2 the result is \frac(x) (2), It seems ok.
