First Answer
1)
3.8 amplitude, period = 1/ [(2/3)/2Pi] = 6Pi/2 =3Pi secs starting point , y = 3.8sin(0)-1.4 = -1.4
2)
73.8 is the amplitude, period = 2Pi/5 secs.
3.8 amplitude, period = 1/ [(2/3)/2Pi] = 6Pi/2 =3Pi secs starting point , y = 3.8sin(0)-1.4 = -1.4
2)
73.8 is the amplitude, period = 2Pi/5 secs.
