Describe the relationship between the amplitude and midline of a periodic function in your own words. REMEMBER A periodic function is a function whose values repeat over regular intervals. The period of a periodic function is the length of the smallest interval over which the function repeats. PRACTICE Wind turbines harness the power of the wind to generate electricity. One particular wind turbine consists of three 100-foot-long rotor blades that rotate around the top of a 150-foot vertical shaft. Use a protractor, a straightedge, and the given graph to estimate the height of the blade tip when the blade is at angles of 0, 30°, 45°, 60° and 90°. The arc on the graph represents a portion of the blade tip's path. Assume the blade rotates counterclockwise and the blade is at an angle of 0 when the blade tip is directly to the right of the top of the vertical shaft. This position is 0° on the graph.
