    Those are all the equations you need to make a simple circuit incorporating a real op amp. What else are you expecting?

    Start with the equation
    V(out) = Aol * (V(in+) - V(in-)), where Aol is the open-loop voltage gain and is very large.

    To get the equation for case 1 or case 2, write KCL equations for the inverting input of the opamp.
