The function h(t) = 5 sin (30(t+3)) is used to model the height of tides. On a different day, the maximum height is the minimum height is -8 and high tide occurs at 5:30am.
Modify function so it matches new data.
The Attempt at a Solution
Answer: h(t) = 8 sin (30(t-2.5))
I know how to get the 8 b/c (8-(-8))/2 = 8
But I don't understand where the 2.5 comes from?
