Hi everybody, here is the result of my session on Sage 7.2 beta0 (but I guess the problem is not specific to that version)
> sage: var('t') > t > sage: integrate(exp(-2*t)/(1-exp(-2*t)),t) > 1/2*log(e^(-2*t) - 1) What does mean log(-1+e^(-2*t)) since the argument is negative ? -- You received this message because you are subscribed to the Google Groups "sage-support" group.
