    MHB Compute Integrals: Integrate (z^3-6z^2+4)dz from -1+i to 1

    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)

    MHB Analytic Function I: Proving f(z)=log z Not Analytic on Domain D w/ γ

    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
