 Sep27 comment Construct a complex function satisfying some conditions!I think I made a mistake, In the last condition, the word "some" should be "any". In the "some" case, it is very easy to construct. Whatever, thank you again!

But I want to know how you get this solution. Jun4 asked An ODE problem(Riccati Equation) May29 comment A problem in complex analysisIt is not a homework. Just a question in a complex analysis book. And I have no idea for this problem. I think Cauchy INT theorem or formula may be useful for this question! May28 asked A problem in complex analysis May27 comment Radius of convergence of Power Series!I think it is not clear in the case $R_1=R_2$, adn WHY $\sum_n(a_n+(-a_n+c_n))x^n$ has a radius of convergence $R_1$? May27 accepted Radius of convergence of Power Series! May27 comment Radius of convergence of Power Series!What about when $R_1=R_2$? May27 comment Radius of convergence of Power Series!Ok I see NOW!
