Can someone please check my work?
y = 4sin((t+4π/3)/2) -2
The generic form is:
y = A*sin(B(t - C)) +D
where A is the amplitude, B is 2π/period, C is the phase shift, and D is the vertical shift
A = 4
period = 4π, so B = (2π)/(4π) = ½
C = -4π/3
D = -2
Putting these values into the above form gives:
y = 4sin((t+4π/3)/2) -2
y = 4sin((t+4π/3)/2) -2
