    What is the Argument of (z+i)/(z-1) when it equals 3π/2?

    thanks a lot! now I hope I can manage the questions on the exam about complex numbers:) don't have to think to difficult..

    What is the Argument of (z+i)/(z-1) when it equals 3π/2?

    I think so, (z+i)/(z-1)= -r i with r = a positive natural number -r i (z-1) = z + i -r i z + r i = z + i -r i z - z = i - r i z (-r 1 -1) = i - r i so z = (i-ri)/(-ri-1) with r = a positive natural number this is it right?:)

    What is the Argument of (z+i)/(z-1) when it equals 3π/2?

    thanks for the welcome:) z would be any number smaller then 0 on the I am axis?

    What is the Argument of (z+i)/(z-1) when it equals 3π/2?

    Homework Statement Hey all. I am trying to get ready for my upcomming calculus exam, but I am kind of stuck here. I have to solve: arg((z+i)/(z-1))=3π/2 Homework Equations ehm none The Attempt at a Solution Tried to fill in z=a+bi: (a+bi+i)/(a-1+bi) then multiply it with its...
