Complex Frequency S, S* and S1, S1*?

    Complex Frequency S, S* and S1, S1*???

    1. The problem statement, all variables and given/known data
    Figure out what the complex frequency S is.
    g(t)=[4e^(-2t)-e^(-t)]cos(4t-95degree)


    2. Relevant equations
    v(t)=K1e^(s1t)+K2e^(s2t)


    3. The attempt at a solution
    I got,
    v(t)=K1e^s1 + K1e^s2 - K2e^s3 - K2e^s4
    Which looks very messy.

    Turns out it gives me,
    s1=-2+j4, s2=-2-j4, s3=-1+j4 and s4=-1-j4
    Which is not a standard form, and I have no idea how to handle four terms...

    Much appreciate any inputs!!!:tongue:
