Thanks Robert, yes, I suspected the numerical integration prematurely. A plot clearly shows that the culprit are the real parts of the hyperbolic functions. plot([tanh(exp(i*t)).real(), (exp(exp(i*t))/cosh(exp(i*t))-1).real()],t,0,2*pi) The two functions are identical, the plot shows different functions. > For realpart(tanh(exp(%i*t))/exp(%i*t*v)) I get: > [...] > Are you getting something different for that? I get for (tanh(exp(i*t))/exp(i*t*v)).real() -e^(imag_part(v)*real_part(t) + imag_part(t)*real_part(v))* sin(imag_part(t)*imag_part(v) - real_part(t)*real_part(v))* tan(e^(-imag_part(t))*sin(real_part(t)))/(tan(e^(-imag_part(t))* sin(real_part(t)))^2*tanh(cos(real_part(t))*e^(-imag_part(t)))^2+1)+ cos(imag_part(t)*imag_part(v) - real_part(t)*real_part(v))* e^(imag_part(v)*real_part(t) + imag_part(t)*real_part(v))* tanh(cos(real_part(t))*e^(-imag_part(t)))/(tan(e^(-imag_part(t))* sin(real_part(t)))^2*tanh(cos(real_part(t))*e^(-imag_part(t)))^2 + 1) Cheers, Peter -- You received this message because you are subscribed to the Google Groups "sage-support" group.
