\(\text{midline}=\frac{\text{max value}+\text{min value}}{2}\)

Since the amplitude of a sinusoid is equal to the vertical distance from its midline to one of its extrema, we can also calculate the midline using one of the following formulas.

\(\text{midline}=\text{max value}-\text{amplitude}\)

\(\text{midline}=\text{min value}+\text{amplitude}\)

I'm going to leave the calculating to you.

I hope this helped,

Gavin
