Middle line
f(t) = y = 0.3
Step-by-step explanation:
To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.
Please see the attached image below, to find more information about the graph
The middle line corresponds to
f(t) = y = 0.3
Maximum amplitude = 0.5
Minimum amplitude = 0.1
Period T = 20π
