Homework Help: Complex Analysis

  1. Jan 14, 2010 #1
    1. The problem statement, all variables and given/known data

    On an Argand diagram, plot ln(3+4i)


    3. The attempt at a solution

    ln(3+4i)
    = ln(3e2(pi)n + 4ei[(pi)/2 + 2(pi)n]
    = i2(pi)n + ln(3+4ei(pi)/2
    = ???

    Where do I go next with this?

    Thanks!
    Andrew

    ln z = ln |z| + i arg(z)

    z = x + iy
