Answer:
We have been given a function and its graph.
[tex]y=4 sin(3t)+2[/tex]
The first point should be midline of the given function
We can see the coordinate of the midline which is (-3.14,2) will be the first point.
And second point should be maximum or minimum.
So, there is minimum according to the graph.
The minimum point will be at when [tex]sin3t=-1[/tex]
[tex]3t=sin^{-1}(-1)[/tex]
[tex]\Rightarrow 3t=-sin^{-1}(1)[/tex]
[tex]\Rightarrow 3t=-\frac{\pi}{2}[/tex]
[tex]\Rightarrow t=-\frac{\pi}{6}[/tex]
[tex]\frac{\pi}{6}=-\frac{1.57}{3}[/tex]
So, the minimum point is:[tex](-\frac{1.57}{3},-2)[/tex]
