Complex number values

  1. Apr 2, 2013 #1
    I have solutions for eigenvalues to be

    λ1=i-1 = √2 e^i(3∏/4) and
    λ2=i+1 =√2 e^i(∏/4)

    How do you go from the i-1 to the next bit for both?

    Just wondering for λ1=i-1 = √2 e^i(3∏/4) , I get the angle phi to be -∏/4 so if the angle is negative do you take it as a rule to add on ∏?

    The angle isn't -∏/4.
    If it were, the corresponding expression would be 1 - i.

    You can add 2∏. When you add ∏, you are multiplying by -1.
