For a certain day, the depth of water, h, in metres in Tofino, B.C at time t, in hours, is given by the formula:
h(t)=7.8+3.5sin[pi/6(t-3)], tE[0,24]. Assume t=0 represents midnight. Provide an algebraic solution to determine the time(s) of day, the water reaches the depth of 10.29m (Give answer in hours and minutes).
see related questions below. Just solve
7.8+3.5sin[pi/6(t-3)] = 10.29
