    complex variable

    im struggling with what seems to be an easy question
    it asks to find [COLOR=rgb(0, 0, 0)]all solutions to the following equations
    - (e^2z)-2i=0
    -(z-i)^5=1
    are two im sure there not hard because he has given us ten to do but just don't see how to do them or is it as simple as jsut breaking them down and putting z=x+iy

    That is the same as e^{2z}=2i so 2z=\log(2i).
    Do you understand the complex logarithm?

    \sin(z)=\sin(x)\cosh(y)+i~\cos(x)\sinh(y)
