The problem here seems to be in the rounding: In [32]: a = log(cos(y) - 1)/2 - log(cos(y) + 1)/2 + 2.99489845376757 - 1j*pi/2 In [33]: a.subs(y, 2).evalf() Out[33]: 3.43792117788449 - .0e-21⋅ⅈ In [34]: a.subs(y,1.1).evalf() Out[34]: 2.50567973267913 -- You received this message because you are subscribed to the Google Groups "sympy" group.
