For me it works. The result is big for humans, but should be no problem for modern computers. I am using FriCAS trunk build using sbcl-1.2.4 (currently with 3Gb limit). Tried also version with 2Gb limit and sbcl-2.2.9 with 1Gb limit. Note I did: res := integrate((x^2+1)^(1/2)/(x^2+(x+(x^2+1)^(1/2))^(1/2)), x); ii := res::InputForm; that is I am _not_ printing resulting InputForm. But I also separately printed the InputForm, it works, just is slow when printing to terminal and useless because the result is much bigger than terminal scrollback buffer. -- Waldek Hebisch -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
