Hi Nathann,

It would be cool to gather the answers to your thread on the wiki...

It was in classroom but more for PhD students/researcher. Very far
behind expectations were:

 - Generating functions. Start from an equation like
     f(t) = sin(t) f'(t) + 1
   and then get information about f (behavior at infinity ? where are
the poles in the complex plane ? what are the coefficients of the
serie expansion ? what is there growth rate ?). There is a well known
maple package for that called gfun which is very powerful.

 - More generally, symbolic computations beyond plotting cos(x) is very limited.

 - Comparison of algebraic numbers. It is currently not possible to
compare two real roots of polynomials (i.e. which one is greater than
the other). Hopefully, I will work on this in january at the pari
workshop ;-)
