3) Critically damped: [math]x(t) = (A + Bt)e^{- \gamma t}[/math] This is the optimally damped case, where the damping coefficient is just large enough to completely quell the oscillations, so the oscillator returns to zero in the least amount of time possible. 4) Overdamped: [math]x(t) = Ae^{- \gamma_{1}t} + Be^{- \gamma_{2}t}[/math]
