Answer:
The middle line for the given function is y=0.
Step-by-step explanation:
The given function is
[tex]f(t)=5\csc(3t-\frac{\pi}{6})[/tex] .... (1)
The general form of csc function is
[tex]f(x)=A\csc(Bx+C)+D[/tex] .... (2)
where, |A| is amplitude, [tex]\frac{2\pi}{B}[/tex] is period, C/B is phase shift and D is middle line.
From (1) and (2), we get
[tex]D=0[/tex]
Therefore the middle line for the given function is y=0.
