1. The problem statement, all variables and given/known data Determine the set on which f(z) = 1/(z^3 +1) is analytic and compute its derivative. 2. Relevant equations Hint: you do not need to appeal to the Cauchy-Riemann equations 3. The attempt at a solution Total stuck with this one. everything we have done this far has been using the c-r equations. Thanks for any input.
