    I have a characteristic equation that yields
    s^3+as^2+s+b=0
    I am supposed to determine the areas in ab-plane that correspond to a stabile system, I just dont know how to begin with, is it Ruth Hurwitz Iam supposed to use?, any hint is welcome:)

    You can certainly use Routh-Hurwitz criterion. Presumably you are considering a linear time-invariant system.

    For your case

    s^3+as^2+s+b=0

    Two conditions must be met


    1. the coefficients of all terms on the LHS of the equation must be greater than zero. So in particular a and b must be greater than zero.
    2. a>b
