MY NOTES Suppose the high tide in Seattle occurs at 1:00 a.m. and 1:00 p.m. at which time the water is 12 feet above the height of low tide. Low tides occur 6 hours after high tides. Suppose there are two high tides and two low tides every day and the height of the tide varies sinusoidally. (a) Find a formula for the function y = h(t) that computes the height of the tide above low tide at time t, where t indicates the number of hours after midnight. (In other words, y = 0 corresponds to low tide.) h(t) = 6 cos 6 (t - 1 ) +6 X (b) What is the tide height at 11:00 a.m.? ft Additional Materials Reading
