    conditions for which inequalitys is true..

    A:
    1-mt<w^2(m+t)

    B:
    -(1+mt)<(w^2 )t(m-t)


    i have 4 cases
    for each case they said that needs to be a condition for which this case would be true
    1: m>t and mt<1
    so they say that i have to demand
    w^2>(1-mt)/(m+t) which is inequality A

    2: m<t and mt<1
    they say that i have to demand
    inequalitys A and B

    why ??
