when evaluating the following code we get 2 different results even tho the same expressions are being evaluated:
%display plain
k,n = var('k,n')
s = n/2 * sum(3/(n+k)^2, k, 1, n)
s.limit(n=Infinity)
%display unicode_art
k,n = var('k,n')
s = n/2 * sum(3/(n+k)^2, k, 1, n)
s.limit(n=Infinity)
whats going on here? why the inconsistency?
