I am trying to do an integration like this:
Ultimately the result I should be able to get is -log(1-z) Manual integration shows that you can integrate(1/(1-z),z) -> -log(z-1), evaluation at the limits yields -log(z-1) - (-log(-1)) which you can simplify to -log(1-z). How can I tell sympy to delay evaluation until after it has done the simplification? I guess that it first does log(-1), which it isn't happy about...
