Grade 12 math: Trig identities/equations? the depth of the ocean at a swim buoy can be modelled by the function d(t) = 4 + 2sin[(pi/6)t], where d is the depth of the water in metres and t is the time in hours, if t is between 0 and 24. Consider a day when t=0 represents midnight. Determine when the depth of water is 3m. answer: t=7, 11, 19, and 23 How do you solve this question? I don't get it.. I got until sin[(pi/6)t] = -1/2...
