>From D(f, x)=0 to compute f, is equal to, for example, eval(f,x,0), thus, it is a constant simplification problem, which I think, is currently missing in fricas: there isn't a "constant simplification function" in 'simplify' or anywhere else (correct me if I'm wrong). If I want to add such functionality, where should I start? Maybe add a pass inside 'simplify'? Example: 4*atan(8) + 4*atan(5) + 8*atan(2) + 4*atan(1/2) - 7*%pi should be zero. -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
