Dear Robert,
Thank you for your message. You actually gave me a great idea. I will
try to investigate if I can recover the questions that Maxima is posing
and display them in the page. In this way only when there are no
questions would the user get the result formula.
Regarding the maxima WIKI plugin, the nice thing about it is that the
image png is actually stored with a name that is the md5 signature of
the input expression. This makes it very easy to find if the expression
needs to be evaluated or if a png result already exists.
All the best,
Antonio Amorim
