RE: Cubic and Quartic Formulae
Xcas and the Prime can compute sum(1/(a^2+n^2),n,0,inf), just try!
I will just not implement Cardan/Ferrari formula in the giac kernel because they are useless as explained earlier, you are of course free to adapt my Xcas program for 3rd order equation if you really want Cardan formula on the Prime.
