Question

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).

Answer 1

see related questions below. Just solve

7.8+3.5sin[pi/6(t-3)] = 10.29
