Connections and maritime applications
Example 1:
The wave height in a bay t hours after midnight is given by the formula f(t)=1.7 sin〖(t/1.9-3)+2〗.
The ship can set sail only if the wave height is below 0.6 m.
a) Determine all time intervals in which the ship can exit the bay. (Help: plot the line representing the height required, then read the intersections).
b) Determine all moments in time for which the height is the largest.
c) Determine all moments when the wave height is 2 m.
