Chapter 5, Problem 5.6.187(choose chapter or problem)
This activity should result in an unusual group display entitled Frere Jacques, a New Perspective. Here is the touch-tone phone sequence: Group members should write every sound in the sequence as both the sum of sines and the product of sines and cosines. Use the sum of sines form and a graphing utility with a [0, 0.01, 0.001] by viewing rectangle to obtain a graph for every sound. Download these graphs. Use the graphs and equations to create your display in such a way that adults find the trigonometry of this naive melody interesting.
