(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

High tide at 4am with a depth of 6 meters. Low tide at 10 am with a depth of 2 meters. Model the problem using the equation to show the depth of the water t hours after midnight.

2. Relevant equations

y= A cos(Bx+C) +D

3. The attempt at a solution: I am not getting the values that I should I think.

I have A=2, D=4, B=pi/6, C=pi/6. They don't seem right though.
