In this exercise you can synthesize sounds by superimposing sine and cosine waves.  You can then listen to those sounds.

• Open the Fourier Series Simulation.
• Explore the interface.  For instructions click "Full Directions".
• Compare the sounds for a sine, cosine, square, triangle and saw tooth wave with the same fundamental frequency.
• Describe the frequency content of those waves and how they sound to you.
• Synthesize you own waves. Observe and listen.
