The most common command for numerical summation isevalf(Sum(f, x=a..b))where the summation command is expressed in inert form to avoid first invoking the symbolic summation routines. It is also possible to invokeevalfon an unevaluated sum returned by the symbolicsumcommand, as inevalf(sum(f...
There is no unique inverse to the sum() command. Think about it. If I tell you that 2+2 equals 4, there is no way to for you to undo that, and obtain 2 and 2 from 4. It could have been 1 and 3, or 0 and 4, or -1.1 and 5.1, etc.u...
