The "drives with greater amplitude". Resonance requires an amplification of amplitudes not just adding two waves. Otherwise, adding any signal between 90 and -9

The "drives with greater amplitude".
Resonance requires an amplification of amplitudes not just adding two waves. Otherwise, adding any signal between 90 and -90 degrees out of phase would constitute 'resonance'.

If you put one in the feedback path of an op-amp you'll meet the criteria described by the physics definition but putting that same component on the input of the op-amp may result in an undetectable signal.
