Dunno if it matters but maybe you can handle this directly in Maxima. foo : sum (1/(k + m)^3, k, 1, inf); load (simplify_sum); simplify_sum (foo); => -psi[2](m+1)/2 ev (%, m=2); => zeta(3)-9/8 ev (%, numer); => .07705690315959424 Maybe there's a convenient way to do that through Sage, I don't know. simplify_sum applies the various summation methods known to Maxima, including the Gosper and Zeilberger methods and some others.
