Ok, thank you. I see: >>> from sympy import * >>> -polylog(2, exp_polar(I*pi))/16 + pi**2/96 -polylog(2, exp_polar(I*pi))/16 + pi**2/96 >>> exp_polar(I*pi) exp_polar(I*pi)
Then should not this gives me pi**2/64 ? >>> -polylog(2, -1)/16 + pi**2/96 pi**2/192 -- You received this message because you are subscribed to the Google Groups "sympy" group.
