Actually, this is a proper bug in FriCAS, because the translation of your integral is
integrate((%i*a*tan(d*x + c) + a)*sec(d*x + c)^10, x) (note the "%i" instead of "I", which is FriCAS' complex unity, "I" is just any other variable for FriCAS) The result of the above integral is >> System error: arithmetic error DIVISION-BY-ZERO signalled Operation was /, operands (2199023255552 0). which cannot be handled by the sage FriCAS interface at the moment. I believe a similar problem was reported before, but maybe this one is easier to fix. Martin Am Sonntag, 19. Januar 2020 20:36:02 UTC+1 schrieb Nasser M.
