Amass is suspended from a cable to form a pendulum. when the mass is displaced from its resting position and allowed to swing, the displacement of the mass relative to its resting position is periodic. what is the general form of a trigonometric function with amplitude and frequency that could model the displacement of the mass relative to its resting position as a function of the time after passing through the resting position?
