Integrals that       must be split manually in order to be evaluated successfully should be       counted as 100% failed in my view - an Algebra System should go beyond a       Table of Integrals with only so many entries.              Sadly, I am now finding that the FriCAS web interface refuses to respond       after I submitted a pseudo-elliptic integral mentioned in a post of       Sat, 20 Aug 2016 08:46:09 +0200 to another thread earlier today while       forgetting to invoke setSimplifyDenomsFlag(true) first:               integrate((1 + x)/((1 + x + x^2)*(2 + x^3)^(1/3)), x) = ?              Offering his most contrite apologies,              Martin :((.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
