Simple complex logarithm HELP PLEASE

  1. Oct 28, 2009 #1
    1. The problem statement, all variables and given/known data
    e^z = e
    e^z = e^-z


    2. Relevant equations
    they are the first 2 questions on my hw and my book is so bad i dont even know how to get the right answers, i've been online for over an hour i'm i'm sure they are easy.

    3. The attempt at a solution
    ffirst one just guessing ?
    z = 1 ???
    second in the back of the book says z = i*k*pi k = 1, 2, 3..

    What can you say about ex+iy for x and y real numbers?

    e^x(cos(y) + isin(y)) = e??
    i got that ones, i feel like i'm being really dumb and just not seeing something really simple

    What? That doesn't make any sense. You should review how to calculate ex+iy by splitting it up into exeiy and calculating eiy
