Are damped and/or resonant oscillations sinusoidal?

[MDJH]

If we're to simplify damped and resonant oscillations by assuming that there is some specific pattern with which the oscillation's amplitude either decreases (damped) or increases (resonant) then is it still sinusoidal or does it qualify as something else?

It would still be sinusoidal.

Damping in a sinusoidal system we call it an overshoot isn't it?
