The formula for a cosine function that models the variation in inches above and below the water level as a function of time in hours since 9:15 a.m. is:
f(t) = 20cos(π/6 * (t+3.25)) + 32
Where:
- f(t) is the variation in inches above and below the water level
- t is the time in hours since 9:15 a.m.
f(t) = 20cos(π/6 * (t+3.25)) + 32
Where:
- f(t) is the variation in inches above and below the water level
- t is the time in hours since 9:15 a.m.
