Re: Analytic function III Already try hard but I really stuck on this question Please help

I am trying to first separate them to integrate individual z^3dz, -6z^2dz and 4dz. Line integral γ(t)= t*i+(1-t)*(-1-+i)

Let p(z)=A(z-z1)...(z-zn) where A and z1...zn are complex numbers and A not equal to 0 . Show that P'(z)/P(z)=∑ (1/(z-zj)) z not equal z z1...zn

Integrate (z^3-6z^2+4)dz where the function is any curve joining -1+i to 1. Z is complex number

Prove f((z) = log z cannot be analytic on any domain D that contains a piecewise smooth simple closed curve γ that surrounds the origin? Thanks
