2021-07-18 16:50:07 +0200	marked best answer	Sage refuses to evaluate summations... I'm trying to define a function `g(x) = sum(frac(jp/q), j, 0, x)` where `p`, `q` are pre-defined constants (say `(p, q)=(33, 21)`). Sage did not give any errors, but when I type `g(10)`, I would get output symbolic expression `sum(frac(11/7j), j, 0, 10)`, which is different from the expected value `31/7`. How do I fix this?
