	/// Example03: A Sinusoidally Driven String
	/// The string shown in Figure 16.10 is driven at a frequency 
	/// of 5.00 Hz. The amplitude of the motion is 12.0 cm, and the 
	/// wave speed is 20.0 m/s. Determine the angular frequency \omega 
	/// and wave number k for this wave, and write an expression 
	/// for the wave function.
	/// \omega = 31.4 rad/s
	/// k = 1.57 rad/m
	/// y = 0.12 \sin(1.57x - 31.4t)
