High tide occurs at 8:00AM and is 2m above sea level. Six hours later, low tide is 2m below sea level. After another 6h, high tide occurs (again 2m above sea level), then finally one last low tide (6h later, 2m below sea level). (a) write a mathematical expression that would predict the level of the ocean at this beach at any time of day. Set t=0 to midnight. It may help to draw a sketch first. (b) Find the...

1. You are on the beach in Wasaga Beach, Ontario. At 2:00 PM on June 15th, the tide is high. At that time you find that the depth at the end of the pier is 1.5 meters. At 8:00 pm the same day, the tide is low, and you find that the depth of the water is 1.1 meters. Assuming the depth of the water varies sinusoidally with time: a) Identify the key features of the sinusoidal function, and use...
Tides are cyclical phenomena caused by the gravitational pull of the sun and the moon. On a particular retaining wall, the ocean generally reaches the 3 m mark at high tide. At low tide, the water reaches the 1 m mark. Assume that high tide occurs at 12:0
Tides are cyclical phenomena caused by the gravitational pull of the sun and the moon. On a particular retaining wall, the ocean generally reaches the 3 m mark at high tide. At low tide, the water reaches the 1 m mark. Assume that high tide occurs at 12:00 p.m. and at 12:00 a.m., and that low tide occurs at 6:00 p.m. and 6:00 a.m. What is the height of the water at 10:30 a.m.? https://gyazo.com/baa597e87fe32170ec4f7ea775182860

3. The depth of the water (in meters) at a certain pier is given by the equation: d)2+ sint, where t is the number of hours after 10:00 AM. 2 a) How deep will the water be at high tide, and at low tide? b) Mid-tide occurs when the height of the water is exactly midway between the high and low tides. Counting time after 10:00 AM, what are the first two times when it is mid-tide? c) How many...

High tide occurs at 8:00AM and is 1m above sea level. Six hours later, low tide is 1m below sea level.

Here's all the information I have
A certain bay with very high tides displays the following behavior. In one 12-h period the water starts at mean sea level, rises to 19 ft above, drops to 19 ft below, then returns to mean sea level. Assuming that the motion of the tides is simple harmonic, find an equation that describes the height of the tide in this bay above mean sea level. (Let y be the height above sea level in...
