Hello
I looking for a way to transform an expression in the form
Sum[a[n], {n, 1, Infinity}] + Sum[b[n], {n, 1, Infinity}]
to :
Sum[a[n]+b[n], {n, 1, Infinity}]
where a[n] and b[n] are numerical.
I tried quite a faw Mathematica fuctions, but none of the gives the required
result.
There is still the possibility to define custom transformation rules, but
Mathematica should provide a function for doing that.
Thank you for your answer.
