Question

A wave is represented by equation x=0.025 cos(3.14z-62.8t), where the distances are in meters and time in seconds. Find the amplitude, speed, the wave length the phase angle and the frequency of the wave. Find the amplitude, the speed, the phase angle, and the frequency of the wave. Find the displacement x at the time t=0.10 s at a point z = 0.50 m.
