Let $g$ be a real number.
I want to prove, for any $n$ and $m$, an equality of the form
$$ \sum_{i=1}^n f_i (m,g) = 0 $$
where the function $f_i$ is a rational function of $m$ and $g$.
Of course it's easy to check this by substituting finite values of $n$, but is there a way in Sage to prove it for any integer?rue82Sat, 13 Feb 2021 21:40:36 +0100https://ask.sagemath.org/question/55699/
