Name: Date: Part B: Application (12 marks) 1. Determine the equation of the following graph using sin 0 . [4] 2 - 2 2. The depth of water off a pier at high tide is 10 meters and I meter at low tide. The tide cycles every 12 hours. a) If the water is at low tide at midnight, draw a graph (fully labeled) to show how the depth of the water changes over the next 24 hours. [3] b) Determine the equation (your choice), using radians, for the water depth, d(t), t hours after low tide. [3] c) Find the depth, to the nearest tenth, of water at 3 hours after low tide [2]
