The depth of water in a tank oscilliates sinusoidally once every 6 hours. If the smallest depth is 5.5 feet and the largest depth is 8.5 feet, find a possible formula for the depth of time inhours.
I say f(x)=6.75+1.25sin(pi/3)
Am I right

Correct.

I believe it should have been
y = 7 + 1.5sin(pi/3)t
