Here is one problem I am stuck on:

At CI State Park, the average height of the tide in feet

*t*hours after hight tide is given by the function

[tex]h(t)=2\cos\left(\frac{2\pi}{13}\left(t-2\right)\right)+4[/tex]

a. What is the smallest positive value of t corresponding to the low tide?

The answer to a is 8:30. How did they come up with this answer?
