Unformatted text preview: can be modeled by a sine or cosine function. Assume there is an interval of 12 hours between successive high tides. a) Sketch the graph of the height if it is 2.6 meters at low tide and 9.6 meters at high tide. b) Use the graph to help express the height of the tide h meters, as a function of the time t hours after high tide. h(t) = 3.5cos 6 t F H G I K J...
