[sage-support] Re: Definite integral disagrees with Maple and mathworld

Thank you for the note. You claim: "For \int_{1/3}^1 fra(1/x) dx Maple returns ln 3 - 1/3". I can't reproduce this on Maple 13 on linux, here is a session: > fra1:=x->1/2+I/(2*Pi)*log(-exp(-2*Pi*I*x)): > ii:=int(fra1(1/x),x=1/3..1); ii := - 5/6 + ln(3) > What abou
