Homework Help: Principal Value of an arguement

  1. Jan 27, 2009 #1
    1. The problem statement, all variables and given/known data

    Ok, I'm just looking for a general answer as to how to find the principal value of an arguement.

    2. Relevant equations

    3. The attempt at a solution
    I know how to find the arguement and that the principal value is between 0 and 2pi, so if I have -1.55 as the arguement, do I just add 2pi?

    In the absence of any countervailing information, yes, that would work.
